Greenland Grab: Trump Squeezes the Alliance as Costa's Twenty-Seven Scramble to Summit

Washington has demanded "Complete and Total Control" of Greenland and put a 10% tariff on eight NATO allies. Europe's answer is an emergency summit — and a rearmament drive that has quietly redrawn the arithmetic of coercion.

What's the problem?

On 17 January 2026, Donald Trump threatened additional tariffs on goods from eight NATO allies—Denmark, Norway, Sweden, France, Germany, the UK, the Netherlands and Finland—unless agreement was reached for the US to purchase Greenland. The proposed rate was 10% from 1 February, rising to 25% from 1 June. On 21 January, following talks with NATO Secretary General Mark Rutte, Trump announced that the tariffs would not go ahead. The trigger was the troops those governments had sent to Greenland for the Danish-led Operation Arctic Endurance; the US president accused them of journeying there "for purposes unknown" European Newsroom. In a letter to Norway's Prime Minister Jonas Gahr Støre, he wrote that the world "is not secure unless we have Complete and Total Control of Greenland" ABC News.

European Council President António Costa has convened an extraordinary meeting of all 27 heads of state and government in Brussels, to be held this week, with. The eight targeted states issued a joint warning of a "dangerous downward spiral" European Newsroom. Costa said tariffs "would undermine transatlantic relations and are incompatible with the EU-US trade agreement" and declared the bloc's "readiness to defend ourselves against any form of coercion" ABC News. The structural danger: the alliance's hegemon is coercing its own members, and Europe has no tested playbook for it.

Is history repeating itself?

Napoleon's Continental System (1806–1812) deployed economic blockade against friends and neutrals alike; its enforcement costs helped drive the Russian disaster and imperial collapse Britannica. Suez 1956 is the closer mirror: Eisenhower's Washington forced Eden's Britain to halt by denying IMF support for sterling, and Eden fell National Army Museum. Both say the same thing — coercing your own side feels cheap and ends expensive. The analogy breaks in one place: Napoleon and Eisenhower both acted against the weaker partner, whereas today's EU is the world's largest single trading bloc with an untested counter-instrument.

Whose plan is better?

The EU's grand strategy of "open strategic autonomy" never priced coercion from inside the alliance; Greenland breaks its central assumption. The plan problem is leadership: Costa and von der Leyen can convene 27 governments, but their mandate is consensus-bound, and past vetoes have hollowed EU–US resolve. Washington's plan is transactional leverage — squeeze Brussels while courting Beijing, with a Trump–Xi summit reported for 24 September (date not independently confirmed). That signals Europe is being managed as the junior relationship.

Whose policy is better?

Three Smart Powers are in play. State (economic security and crisis coordination). Economic — the EU–US trade agreement that Costa says the tariffs would violate, widely reported to carry a 15% tariff ceiling on most EU exports (not re-verified against the primary text this session), and von der Leyen's 16 September State of the Union invitation for Canada to become the EU's first "associate member", moving "from CETA to an Alliance for the Future" Euronews. Diplomatic — holding 27 governments together. France's Emmanuel Macron has said he will request activation of the EU's anti-coercion instrument, the "trade bazooka", in the event of new US tariffs ABC News.

Whose performance is better?

The visible scoreboard: US goods imports from the EU reached $632.9 billion in 2025, up 4.3% ($26.2 billion) on 2024 USTR — the exposure Europe is defending. But Eurostat's Comext series shows the fight already biting: the EU goods surplus with the US narrowed from €80 billion in Q1 2025 to €29 billion in Q2 2026, with exports down 26% against Q1 2025 while imports rose 8% Eurostat.

The deeper shift sits in State Power. NATO reported that European Allies and Canada raised core defence expenditure by nearly 20% in 2025 NATO, and SIPRI puts the 29 European NATO members at a combined $559 billion, with 22 at or above 2% of GDP SIPRI. Performance here is structural rather than momentum: rearmament is converting dependence on the US umbrella into autonomous capability, and SIPRI dates the pace of European NATO spending growth to its fastest since 1953 SIPRI. The rival's hybrid flip — economic coercion fused with a territorial claim — is aimed precisely at stopping that conversion.

Learning from the past, what is the solution?

The European Council should adopt, at the summit, a standing coercion-response protocol: a pre-agreed countermeasure ladder. Actor: the 27, with the Commission as executor. Action: publish the ladder and trigger thresholds in advance. Purpose: deter tariff-by-territory by removing the guesswork. Timeframe: 90 days. Success measure: a published instrument that survives its first veto test. That is what the Continental System's victims lacked.

How much will it cost?

Working derivation, not an official forecast: with US goods imports from the EU at $632.9 billion (2025) USTR, a Greenland-triggered 10% wave touching even a quarter of that flow puts roughly $15–20 billion a year of European exports at direct risk. Label: working derivation from USTR 2025 trade actuals. No official figure exists.

What is the cost of doing nothing?

If Europe cannot answer coercion-by-tariff, every future demand — territory, procurement, alignment on China — arrives with the same template and the same expectation that Brussels concedes. The specific bill sits in that €80bn-to-€29bn surplus collapse Eurostat and in whatever fraction of $632.9 billion Washington decides next to squeeze.
