Collateral Sovereignty: How the Iran War Put the Falklands in Play
When a leaked Pentagon memo from Elbridge Colby floated the idea of reviewing US support for Britain’s claim to the Falkland Islands, most commentators reached for the obvious parallel: Greenland. Another instance of Trump-era territorial revisionism, another ally blindsided.
But this reading misses the deeper mechanism at work. The Falklands gambit is not really about the Falklands. It is about Iran — and, by extension, about Israel.
The Colby memo is explicit: the proposed reassessment of European “imperial possessions” is a punishment for NATO allies who refused to grant the United States access, basing, and overflight rights for the US-Israeli war against Iran. Spain closed its airspace. Britain and France declined to join the naval blockade of the Strait of Hormuz, arguing that doing so would constitute entering the war. The Pentagon’s response is to treat these refusals not as sovereign decisions but as defaults on an implicit contract.
This is where the transactional logic of the new Washington becomes visible. For decades, NATO allies enjoyed American defence guarantees on the implicit understanding that solidarity ran both ways. The premium was paid through burden-sharing: defence spending, interoperability, and operational support when Washington needed it.
The Iran war has revealed that many allies consider this bargain renegotiable. They want American protection when Russia threatens, but refuse to stand alongside America and Israel when Iran threatens. The Colby memo is Washington calling in the debt. The Falklands are the collateral being seized.
Argentina’s President Milei, a shrewd operator and Trump ally, understands this instinctively. His declaration that “the Malvinas were, are, and always will be Argentine” is an opportunistic claim made possible not by anything Buenos Aires did, but by a war against Iran that fractured the Western alliance. That two populist allies of convenience — a self-described libertarian in Buenos Aires and a nationalist in Washington — are now converging on a territorial squeeze on a fellow democracy whose soldiers died alongside Americans in every major conflict of the past century is a development without modern precedent. His foreign minister’s framing of the islands as a “colonial situation” completes the repositioning.
The squeeze, moreover, is not merely rhetorical. It has already been expressed in hardware. The Telegraph has reported that Washington pressured the Foreign Office into standing aside while American-made F-16s were transferred from Denmark to Argentina late last year — bypassing Britain’s longstanding arms embargo. Foreign Office officials were told “in no uncertain terms” not to oppose the deal. Milei called the jets his country’s “guardian angels.” The ostensible rationale was to prevent Buenos Aires from drifting toward Chinese and Russian suppliers, but the effect is unmistakable: the country that claims the Falklands now flies Western combat aircraft acquired despite British misgivings, with American blessing.
For Israel, the implications are profound and double-edged. On one side, the Falklands episode demonstrates the extraordinary gravitational pull of the US-Israel strategic alignment. The bilateral relationship has become so central to American force projection that third-party territorial settlements — arrangements dating back centuries — are now being repriced as a function of where countries stand on Israel’s security. That is a remarkable testament to the depth of the partnership.
On the other side, it reveals a vulnerability. If American alliance commitments everywhere are being revalued through the lens of the Iran war, then Israel’s own security guarantees are subject to the same logic. The pattern has precedent. The Syrian Kurds fought and bled alongside US forces against Islamic State, only to be abandoned to a Turkish incursion when the strategic calculus shifted. Today, Washington rewards those who supported the Iran campaign and punishes those who did not. But transactional logic cuts both ways. Should a future administration decide that the cost of backing Israel is too high, the same framework that is currently weaponising the Falklands could be turned on Jerusalem.
The 2013 Falklands referendum, in which 99.8 per cent of islanders voted to remain British on a 92 per cent turnout, ought to have settled the question permanently. Self-determination is not an option to be exercised or abandoned at the discretion of a third party in Washington. Yet here we are — the most emphatic democratic mandate in modern history being treated as a negotiable instrument because of a war eight thousand miles away.
Downing Street’s response — that sovereignty “rests with the UK” and “nothing is going to change” — is the language of a party insisting a contract remains valid. It may well be right. Britain fought and won a war over these islands in 1982, and the political will to defend them remains bipartisan.
But the deeper lesson is for everyone relying on American security guarantees, Israel included. The post-1945 order was built on the assumption that certain commitments were permanent features of the international architecture. The Colby memo reveals them to be conditional — promises whose durability depends not on shared values or treaty obligations, but on operational utility in the current crisis.
For Israel, which has built its strategic doctrine around the unshakeable nature of the American commitment, this should prompt serious reflection. The Falklands are a stress test. The question is not whether the US-Israel bond is strong today — it plainly is. The question is whether any alliance can remain unshakeable when its guarantor has started treating solidarity as a transactional commodity.
