International organizations, treaties, and soft power
Part A · what diplomacy is and why it exists
The core purpose: managing relations between states without war
"Diplomacy is the art of letting someone else have your way." — Daniele Varè, Italian diplomat
Why diplomacy exists
States have conflicts of interest. War is catastrophically expensive. Diplomacy provides a way to manage these conflicts through communication, negotiation, and agreement rather than violence.
What diplomats actually do
Represent their state's interests in foreign countries. Report on developments. Negotiate treaties and agreements. Protect their citizens abroad. Communicate official positions — and unofficial signals.
The Vienna Conventions
1961 (diplomatic relations) and 1963 (consular relations) set the global rules. Virtually every country in the world is a party. These treaties created the framework that all modern diplomacy operates within.
The diplomatic escalation ladder — from routine contact to breaking relations
1
Routine diplomatic contact
Ambassadors meet foreign ministry officials, official letters, standard bilateral communication. The baseline of any functioning relationship.
e.g. UK ambassador delivers note on a trade dispute
2
Formal protest / démarche
Ambassador formally delivers written objection to the foreign ministry. The language matters: "expresses concern" is mild, "strongly protests" is serious.
e.g. Protest over a border incursion or arrest of a citizen
3
Summoning the ambassador
The foreign ministry summons the other country's ambassador to deliver a reprimand — the host country is demanding explanation, not offering it. Noticeably stronger than a normal visit.
e.g. Germany summons US ambassador over NSA surveillance (2013)
4
Recalling the ambassador "for consultations"
Your own ambassador is recalled home. The phrase "for consultations" is diplomatic fiction — everyone knows it's a protest signal. The embassy continues to function at lower level.
e.g. France recalled ambassador to USA after AUKUS (2021)
5
Expulsion (persona non grata)
Declaring a diplomat persona non grata forces them to leave. Used to expel suspected spies or punish hostile acts. Often met with reciprocal expulsions.
e.g. 153 Russian diplomats expelled by 28 countries after Salisbury poisoning (2018)
6
Breaking off diplomatic relations
Closing the embassy, recalling all staff. Near-complete breakdown — but not war. Communication can still occur through third-party embassies (a "protecting power").
e.g. USA and Iran (since 1980); USA and Cuba (1961–2015)
Part B · the UN system — architecture and members
United Nations (UN)193 member statesfounded 1945
Purpose
Maintain international peace and security, develop friendly relations among nations, promote human rights and international law.
Headquarters
New York (main), Geneva (human rights, humanitarian), Vienna (nuclear, drugs, crime), Nairobi (environment).
Budget
~$3.5B/year (regular budget). Assessed contributions — USA ~22%, China ~15%, Japan ~8%, Germany ~6%.
The UN was founded after WWII by the victorious Allies to prevent another world war. Its founding document, the UN Charter, is effectively the closest thing the world has to a constitution for international order. 193 of the world's 195 recognised states are members. Non-members: Vatican City (observer), Palestine (observer).
General Assembly (UNGA)
193 members — 1 country, 1 vote
All UN members meet here. Passes resolutions by majority vote. Resolutions are non-binding — they represent world opinion but cannot legally compel states. Each September, heads of state make addresses (the "General Debate").
Security Council (UNSC)
15 members — 5 permanent + 10 rotating
The only UN body that can pass binding resolutions — including authorising the use of force, peacekeeping missions, and economic sanctions. The 5 permanent members (P5) each hold a veto. This is where real power sits.
International Court of Justice (ICJ)
15 judges, The Hague
Settles legal disputes between states (not individuals). Cases: border disputes, treaty interpretation, state responsibility. Judgments are technically binding but enforcement depends on the Security Council — a P5 member can block enforcement of a ruling against itself.
International Criminal Court (ICC)
124 member states, The Hague
Tries individuals (not states) for war crimes, crimes against humanity, and genocide. Separate from the UN. The USA, Russia, China, India, and Israel have not ratified the Rome Statute. Has issued arrest warrants for Putin (2023).
Secretariat / Secretary-General
~44,000 staff worldwide
The UN's administrative body. The Secretary-General (SG) is the world's chief diplomat — António Guterres (Portugal) since 2017. The SG can use "good offices" to mediate conflicts but has no independent power to compel states.
UN Specialised Agencies
15+ autonomous organisations
WHO (health), UNESCO (culture/education), FAO (food), UNICEF (children), UNHCR (refugees), ILO (labour), IMF (finance), World Bank (development), IAEA (nuclear). Each has its own membership, budget, and governance.
UN system — simplified architecture
Part C · the Security Council and the veto — the most powerful diplomatic mechanism
The P5 and their veto power
USA
P5 since 1945
~90 vetoes total; 40+ to protect Israel; Cold War bloc
Russia
USSR seat → Russia (1991)
Highest count (~140+ USSR/Russia combined). Blocks action where it has interests
China
ROC seat → PRC (1971)
Used veto sparingly until ~2010; now more assertive, often with Russia
UK
P5 since 1945
~32 vetoes, mostly Cold War era. Often votes with USA and France
France
P5 since 1945
~18 vetoes; pledged not to veto on genocide/mass atrocity cases
Note: figures include USSR-era votes for Russia; counts vary slightly by source. China figure is PRC since 1971.
How the veto works
A resolution needs 9 votes to pass. But if ANY of the 5 permanent members votes "no," the resolution fails regardless of how many others voted yes. Even 14-1 is a failure if the 1 is a P5 member. An abstention is NOT a veto — it allows the resolution to pass if enough others vote yes.
Why it exists and why it's controversial
The veto was the price of P5 participation in 1945 — the great powers would only join if they couldn't be outvoted. Without it, the UN wouldn't exist. Critics: it allows the P5 to protect themselves and their allies from accountability. Any reform requires P5 agreement — which they'll never give.
Recent examples
Russia vetoed every UNSC resolution on Syria (2011–2023), blocking any authorised intervention despite 500,000+ deaths. Russia vetoed resolutions condemning its 2022 invasion of Ukraine. The USA regularly vetoes resolutions critical of Israel. China and Russia have jointly vetoed resolutions on Myanmar and Venezuela. The veto means that wars involving P5 members or their close allies are almost always immune from UNSC action.
Part D · major international groupings — click to explore
Membership overlap — selected blocs (approximate % of world GDP)
Share of global GDP (nominal, approximate). G20 includes EU as non-enumerated member.
Part E · special diplomatic formats — why odd groupings exist
5+1 (P5+1 / E3+3)
Iran nuclear negotiations
The 5 UN Security Council permanent members plus Germany (the +1). Germany was included because of its economic weight and EU role — not because it's a nuclear power. This format produced the JCPOA (Iran nuclear deal) in 2015, from which the USA withdrew in 2018. The format illustrates how ad hoc groupings form around specific issues when the UN framework is too unwieldy.
Normandy Format
France, Germany, Russia, Ukraine
Created in 2014 after Russia annexed Crimea, meeting in Normandy on the D-Day anniversary. France and Germany mediated between Russia and Ukraine. Produced the Minsk Agreements (I and II). Collapsed with Russia's full-scale invasion of February 2022. Illustrates how bilateral conflicts often require third-party mediators to create a table that both sides will sit at.
Six-Party Talks
North Korea's nuclear programme
USA, North Korea, South Korea, China, Japan, Russia. Began 2003, collapsed 2009. China is included as the key interlocutor with Pyongyang. North Korea has since developed a full nuclear arsenal. The talks illustrate the difficulty: North Korea sees nuclear weapons as regime survival, not a bargaining chip.
Quartet on the Middle East
UN, USA, EU, Russia
Established 2002 to coordinate positions on the Israeli-Palestinian peace process. Effectively inactive since ~2014. Its failure illustrates a common pattern: multi-party formats that include actors with conflicting interests often produce statements but no action.
Contact Group / Ramstein Group
Ad hoc for specific crises
The Ukraine Defence Contact Group (Ramstein Group) — 50+ countries coordinating military support for Ukraine. These form because the formal UN mechanism is blocked by a veto and states need another framework for coordination. A Contact Group is any informal grouping of states with an interest in resolving or managing a specific conflict.
Minsk Agreements
Ukraine conflict 2014–2022
Two ceasefire agreements (Minsk I: 2014, Minsk II: 2015) brokered by France and Germany. Neither was fully implemented. Russia invaded on a large scale in February 2022, rendering them moot. Studied as a case of how agreements fail when one party treats them as delay tactics rather than genuine settlement.
Part F · sanctions, immunity, and practical diplomacy
Sanctions
Economic coercion short of war
Restrictions on trade, finance, travel, or technology intended to change a state's behaviour. Types: comprehensive (all trade — North Korea, Iran), sectoral (specific industries — Russian energy, arms), targeted/smart (specific individuals — asset freezes, travel bans). Effectiveness is debated: Iran has been sanctioned for 40 years without abandoning its nuclear programme. Sanctions hurt ordinary citizens more than leaders with offshore wealth.
Diplomatic immunity
Diplomats cannot be arrested or prosecuted
Under the 1961 Vienna Convention, diplomats (and their families) are immune from criminal prosecution and civil suits in the host country. The rationale: if states could imprison each other's diplomats, communication would cease. Embassies are inviolable — the host government cannot enter without permission. Abuse: diplomats sometimes use immunity to avoid traffic fines (~$16M owed in New York alone) or escape more serious charges.
Persona non grata
Diplomatic expulsion
A host state can declare a diplomat "persona non grata" (unwanted person) without explanation, requiring them to leave. Used to expel suspected spies, punish hostile acts, or signal displeasure. After Russia's 2018 Novichok poisoning in the UK, 28 countries expelled 153 Russian diplomats — the largest collective expulsion in history. Russia reciprocated.
Breaking off diplomatic relations
The nuclear option of diplomacy
When a state closes its embassy and recalls its ambassador, it signals near-complete breakdown. Communication can still occur through third-party embassies (a "protecting power"). USA and Cuba had no diplomatic relations 1961–2015 (54 years). USA and Iran since 1980. The break creates problems: no visa services, no consular protection for citizens, intelligence gaps.
Back-channel diplomacy
Secret, informal negotiations
Official negotiations often cannot proceed in public — domestic politics, face-saving, and inflexibility make open talks fail. Back channels are unofficial, deniable contacts that explore compromise. Oslo Accords (1993 Israel-PLO) began as back-channel talks in Norway. Nixon's opening to China (1972) was prepared by Kissinger's secret trip to Beijing. Most major diplomatic breakthroughs began in back channels.
Soft power vs hard power
Attraction vs coercion
Hard power: military force or economic coercion. Soft power (Joseph Nye's concept): the ability to attract and co-opt rather than coerce — through culture, values, and institutions. The USA's soft power includes Hollywood, universities, the dollar, and the idea of the "American dream." China invests heavily in soft power (Confucius Institutes, BRI infrastructure). The most effective states use both (smart power).
Part G · diplomatic vocabulary — click to explore
Part H · how to read diplomatic language — the signal ladder
Every word in a communiqué is chosen deliberately
Diplomatic documents have a precise internal hierarchy of language. The gap between "notes" and "strongly condemns" is enormous. This chart maps approximate signal strength.
"Notes" / "Takes note of"
Barely registers. Acknowledges existence without endorsement. Often used when agreement on stronger language is impossible.
"Expresses concern"
Mild disapproval. Does not demand action. Often the maximum consensus language when states disagree.
"Deplores" / "Urges"
Stronger disapproval or demand. "Urges" implies a request; "demands" implies a requirement. "Deplores" is stronger than "regrets."
"Condemns" / "Demands"
Formal condemnation or binding-style demand. In UNSC resolutions, "demands" carries legal weight and implies consequences.
"Strongly condemns"
Maximum diplomatic censure short of sanctions or force. Achieving unanimous "strongly condemns" in the UNSC is a significant diplomatic outcome.
What to notice in any diplomatic statement: What is absent is often as important as what is said. If a G20 communiqué discusses every major issue except Ukraine, the omission is itself news. Look for qualifiers ("most members," "some delegations") — they signal failed consensus. Look for passive voice ("violations were noted") vs active attribution ("Russia violated"). Active attribution is stronger and harder to agree.
Part I · the power spectrum — hard, soft, and sharp power
How states project influence
Hover over each marker to see what kind of power it represents. The spectrum runs from direct coercion (hard) to indirect attraction (soft) — with "sharp power" (manipulation/subversion) as a separate dimension.

Sharp power — a term coined in 2017 — sits outside the hard/soft spectrum. It describes the manipulation of information, media, and institutions by authoritarian states to distort rather than persuade: disinformation campaigns, funding foreign political parties, manipulating diaspora communities, infiltrating universities. China and Russia are the primary examples. Unlike soft power (which works by being genuinely attractive), sharp power works by corrupting the information environment in the target country.
Part J · major diplomatic milestones — the architecture of the modern world order
1648
Peace of Westphalia
Ended the Thirty Years' War. Established the concept of state sovereignty — the idea that rulers are supreme within their borders and should not interfere in each other's internal affairs. The entire modern international system rests on this principle.
1815
Congress of Vienna
After Napoleon, the great powers redrew Europe. Created the Concert of Europe — a system of regular great-power consultations to manage disputes. The first proto-international institution. Also codified diplomatic precedence and the rules of ambassadorial seniority still used today.
1864 / 1949
Geneva Conventions
The first (1864) established rules for treatment of wounded soldiers and the Red Cross. Four conventions (1949) and additional protocols set the core rules of international humanitarian law: protection of civilians, prisoners of war, the wounded. Ratified by 196 states — more than the UN itself.
1919
League of Nations / Treaty of Versailles
The first attempt at a universal international organisation for peace. Failed: the USA never joined (Senate rejection); it couldn't prevent Japanese aggression in Manchuria, Italian aggression in Ethiopia, or German rearmament. But it established the template that the UN improved upon.
1944
Bretton Woods Conference
Created the IMF and World Bank. Established the US dollar as the world's reserve currency (pegged to gold). The architecture of the post-war financial system. The dollar's reserve currency status — still in place today, even after the gold peg ended in 1971 — remains the foundation of American financial power.
1945
UN Charter signed (San Francisco)
51 original member states. Created the Security Council, General Assembly, ICJ, and Secretariat. The preamble opens: "We the peoples of the United Nations, determined to save succeeding generations from the scourge of war…" The closest thing to a world constitution.
1948
Universal Declaration of Human Rights
Non-binding but enormously influential. 30 articles covering civil, political, economic, social, and cultural rights. The foundation of international human rights law. Notable: it was drafted by a committee that included Eleanor Roosevelt (USA), René Cassin (France), Charles Malik (Lebanon), and Peng Chun Chang (China) — deliberately cross-cultural.
1961
Vienna Convention on Diplomatic Relations
Codified the rules of diplomacy: inviolability of embassies, diplomatic immunity, rules for persona non grata declarations. 193 state parties — effectively universal. Without this framework, every bilateral relationship would need to negotiate its own rules from scratch.
1968 / 1970
Nuclear Non-Proliferation Treaty (NPT)
The central arms control treaty. Three pillars: non-proliferation (non-nuclear states won't develop weapons), disarmament (nuclear states will reduce arsenals), peaceful use (all states can access nuclear energy). 191 state parties. Non-signatories: India, Pakistan, Israel (undeclared nuclear power), North Korea (withdrew 2003).
1993 / 1995
Oslo Accords / WTO founded
Oslo Accords: the first direct Israel-PLO agreement, produced through Norwegian back-channel diplomacy. Led to Palestinian Authority but failed to produce final-status agreement. WTO replaced GATT, creating binding trade dispute settlement for the first time.
1998
Rome Statute → ICC (2002)
Created the International Criminal Court — the first permanent international court with jurisdiction over individuals for the worst crimes. 124 states have ratified. The USA signed but unsigned under George W. Bush; Russia similarly unsigned. The court's reach is limited by non-participation of major powers.
2015
Paris Agreement on Climate
196 parties. Each state sets its own "nationally determined contribution" (NDC) — there is no binding enforcement mechanism for the targets themselves, only binding requirements to report and update. The USA withdrew in 2020, re-joined 2021, and withdrew again in 2025. Illustrates the limits of international law when states lack domestic political will.

Part L · flags of the world

Part M · test yourself
1. Russia vetoes a UN Security Council resolution condemning its invasion of Ukraine. The resolution had 13 votes in favour. What happens next, and what options does the international community have?
The resolution fails — one P5 veto defeats it regardless of other votes. Options: (1) The General Assembly can be convened under "Uniting for Peace" procedure (used in 1950 for Korea), where it can pass non-binding resolutions by 2/3 majority — the GA passed several resolutions condemning Russia in 2022 with overwhelming majorities (141-5, 143-5), though non-binding. (2) States can impose unilateral sanctions outside the UN framework — the EU, USA, UK, and others did exactly this. (3) Arms supplies to Ukraine outside the UNSC — this happened through NATO and bilateral agreements. The veto means the UN cannot authorise peacekeeping or enforcement, but it cannot stop states from acting unilaterally or in coalition. The war in Ukraine illustrated both the limits of the UNSC (paralysed by the Russian veto) and what diplomacy outside the UN framework looks like.
2. What is the difference between an ambassador and a consul, and why do countries have both?
An ambassador represents their state to the host government — they conduct political diplomacy, attend to state-level relations, and are based in the capital city. A consul represents their state's interests to private citizens and businesses in a specific city — they issue visas, help citizens in distress, authenticate documents, and support trade. A country might have one ambassador in Berlin but consulates in Hamburg, Munich, and Frankfurt to serve the large German cities. Ambassadors are accredited to the head of state; consuls are not. Diplomatic immunity is stronger for ambassadors; consular immunity is more limited.
3. Why does Germany have a permanent seat in the G7 but not the UN Security Council?
Because the two institutions were created at different times with different logic. The UN Security Council was designed in 1945 around the victorious Allied powers — the USA, USSR, UK, France, and China (ROC, replaced by PRC in 1971). Germany was a defeated enemy state; giving it a veto on global security would have been unthinkable. The G7 was created in 1975 around economic weight — the largest industrialised democracies at that time. By then West Germany was the world's third largest economy and naturally included. The frozen 1945 structure of the UNSC means Germany (the world's 4th largest economy, with 84M people) has no permanent representation, while France (similar size) has a permanent seat and veto. This is one of the main arguments for UNSC reform — but reform requires P5 consent, which would mean diluting their own power.
4. What does it mean practically when a country "imposes sanctions" on another country?
Sanctions are legal restrictions that prevent your own citizens and companies from doing business with the target. A country imposing sanctions on Russia prohibits its own banks from processing Russian payments, its companies from exporting certain goods to Russia, and specific Russian individuals from entering or holding assets in the sanctioning country. Secondary sanctions go further: threatening to punish third-country companies that do business with the sanctioned state (the USA uses these aggressively — a Chinese bank that processes Russian payments risks losing access to the US financial system). Sanctions don't require the target's agreement — they restrict your own side's behaviour.
5. Why do the Oslo Accords illustrate both the power and limits of back-channel diplomacy?
The power: the Oslo process succeeded in producing an agreement precisely because it was secret. In public, Israeli and PLO leaders couldn't negotiate — domestic audiences on both sides would have punished any sign of compromise. The back channel in Norway allowed exploratory talks without commitment; neither side had to defend what was discussed. This enabled mutual recognition — Israel recognised the PLO as the representative of the Palestinian people; the PLO recognised Israel's right to exist. The limits: the agreements deferred the hardest issues (Jerusalem, refugees, final borders) to "final status negotiations" that never succeeded. Israeli PM Rabin was assassinated by a nationalist Israeli in 1995 partly because of the agreements; the peace process effectively ended. The lesson: back-channel diplomacy can produce agreements that public diplomacy cannot, but it cannot substitute for the political will to implement them.
6. The USA uses the dollar as a weapon of financial diplomacy. Explain what this means and why it's so powerful.
Because the dollar is the world's primary reserve currency and most international trade (including oil) is denominated in dollars, virtually every bank in the world needs access to the US financial system. The USA exploits this by using secondary sanctions: threatening foreign banks with exclusion from the US financial system if they process transactions with sanctioned countries or entities. A German, Chinese, or Indian bank that clears a payment for a sanctioned Russian entity risks losing its correspondent banking relationships in New York — which would effectively shut it out of international finance. This gives the USA enormous extraterritorial leverage over transactions that have nothing to do with the USA geographically. It's the financial equivalent of controlling the world's shipping lanes. The downside is that overuse of dollar weaponisation gives other countries strong incentives to create alternative payment systems (China's CIPS, Russia's SPFS, BRICS discussions about alternative reserve currencies) — slowly eroding the dollar's dominance and with it, American financial power.
7. Switzerland has been "neutral" for over 200 years. What does that actually mean in practice, and where are the limits?
Swiss neutrality means it does not join military alliances, does not participate in armed conflicts between other states, and hosts neutral diplomatic facilities (ICRC, many UN agencies, the WTO, countless negotiations). It's codified in international law since the Congress of Vienna (1815) and the Treaty of Paris — other states formally recognised Switzerland's neutrality. In practice: Switzerland maintains a military (for self-defence), does participate in UN peacekeeping operations in some capacities, and is a full member of the UN (since 2002), OSCE, and Council of Europe — multilateral bodies that don't constitute military alliances. The limits showed themselves in 2022 when Switzerland adopted EU sanctions against Russia — breaking its tradition of economic neutrality for the first time in decades, responding to domestic and allied pressure. Critics of Swiss neutrality point to WWII: Switzerland processed Nazi gold, maintained trade with Germany, and turned back Jewish refugees at the border — pragmatic neutrality that often favoured the stronger party.
