Each page is built the same way: a timeline of documented events, the standing architecture of treaties and dependencies, the ruptures, and the questions the page has not settled. Every claim carries an evidence tier and its own sources.
Ruptures get their own section on every page. A relations page that lists only cooperation is advocacy — the moments a relationship failed are where its real terms become visible.
An alliance built on dependency rather than sentiment — nuclear delivery, signals intelligence and basing, each established in the 1940s–60s and none of it symmetrical.
The largest cumulative recipient of US assistance, bound by memoranda rather than a mutual-defense treaty — and a relationship that has been suspended, sanctioned, and spied on from both sides.
Security for oil since a shipboard meeting in 1945, with the terms never written as a treaty — and a relationship that has embargoed the United States, been sued by it, and been designated its ally, in that order.
A peace treaty converted into an annual appropriation — $1.3 billion a year in military financing since 1987 — with a relationship that the United States has both walked out on and bought back.
A constitution written under occupation that forbids war, a treaty that makes the United States its guarantor, and a currency revalued by five men in a hotel — the most complete dependency in the section, and one that has been shocked from the American side twice.
The relationship that built the manufacturing base the United States now calls a threat — by policy, in stages, with the documents public — and the only one in the section where an embassy was bombed and a warplane forced down.
The deepest integration the United States has with any country, held together by a trade agreement renegotiated under tariff threat, a water treaty from 1944, and the largest flow of remittances on earth — with a border that was itself the outcome of a war.
One shared air-defense command, a demilitarized border since 1817, the largest foreign source of US crude oil by a wide margin — and a trade relationship renegotiated under tariff threat often enough that the disputes have numbered rounds.
Not yet researched. Listed with the structure that makes each worth documenting, so the queue is a research agenda rather than a promise.
Occupation to basing to energy: the only country where the US both wrote the postwar settlement and later acted against its industrial interest. Nord Stream is the test case.
A relationship deliberately left undefined since 1979, now carrying the majority of advanced semiconductor fabrication. Strategic ambiguity as policy, and what concentration of one industry does to it.
1953 is declassified: the CIA has acknowledged its role in removing Mosaddegh. Everything since — 1979, the tanker war, the JCPOA, 2026 — runs from a documented intervention.
The 1994 Budapest Memorandum traded the world's third-largest nuclear arsenal for assurances that were deliberately not a treaty. What that word was doing is the whole question.
Alliance and proliferation at the same time: aid cycles keyed to US wars in Afghanistan, alongside the A.Q. Khan network. Two policies that could not both be working.
Seventy years of troop presence and an operational-control arrangement in which a sovereign state's forces would pass to a US commander in war. The clearest case of security in exchange for command.
A NATO member expelled from the F-35 program for buying Russian air defense, while hosting US nuclear weapons at Incirlik. An alliance held together by geography alone.
ANZUS, Pine Gap and AUKUS: the most complete intelligence integration outside the UK, and a submarine procurement that reorganized three countries' industrial policy.
The ally that left NATO's command structure in 1966 to keep an independent deterrent, and the one AUKUS cost a contract in 2021. Autonomy inside an alliance, tested twice.
The 2008 civil nuclear agreement admitted a non-signatory of the Non-Proliferation Treaty to nuclear trade. The exception explains more about the NPT than the treaty does.
A sixty-year embargo and a naval base held on a lease the host state does not recognize but cannot end. The clearest surviving artifact of the 1903 order.
A country created around a canal, the canal handed back in 1999, and an invasion in between. Infrastructure as the reason a state exists.
Colony, then bases, then eviction by the Senate in 1991, then invited back under a 2014 agreement. The only case of a full cycle out and back.
The largest proven oil reserves on earth under sanctions, with US refineries built for exactly that grade of crude. The mismatch is the story.
The arms-control architecture — SALT through New START — is the only place these two states wrote binding limits on each other. Most of it has now lapsed, and the lapse dates are public.
War, embargo, normalization in 1995, and now a manufacturing partner positioned against China. The full arc from adversary to supply chain inside one lifetime.
