European Union prepares nuclear trade option responding to Trump tariff demands
- EU’s
ACI counters economic coercion threats. - Nuclear
option targets trade, services access. - Activated
by Commission, qualified majority vote. - Retaliates
against Trump’s tariffs, market restrictions.
Brussels (Washington Insider Magazines) January 20, 2026
– The European Union considers activating its Anti-Coercion Instrument
(ACI) following US President Donald Trump’s threats of new tariffs on eight
European nations unless Greenland transfers to American control. French
President Emmanuel Macron urged the EU not to hesitate using this ‘nuclear
option’ amid emergency diplomatic consultations. The ACI, adopted in 2023 and
unused to date, enables countermeasures beyond tariffs including public
procurement restrictions and investment screening targeting US economic
interests.
EU diplomats convened emergency meetings after Trump’s
Saturday statement linking Greenland sovereignty to tariff relief for NATO
allies. The ACI process allows Commission investigation within four months
followed by qualified majority Council approval enabling rapid responses to
economic pressure. Commission President Ursula von der Leyen confirmed
readiness while prioritising negotiation amid transatlantic trade tensions.

Thule Air Base under defence agreements complicating sovereignty demands. EU
foreign ministers scheduled consultations Tuesday addressing potential ACI
activation against tariff escalation.
Trump administration officials outlined 20-60 percent import
duties targeting EU steel automobiles and digital services unless Greenland
negotiations advance. As reported by Reuters Brussels correspondent Foo Yun
Chee, EU ambassadors discussed reactivating €93 billion countermeasures from
2018 alongside ACI deployment Monday evening.

Macron advocated unified EU response preventing individual
member state concessions to US pressure. French diplomats confirmed Paris
coordination with Berlin pushing Commission activation request formalising ACI
procedure commencement.
ACI legislative framework 2023 regulation detailed
provisions
Regulation (EU) 2023/2675 entered force December 9, 2023
following 2021 Commission proposal responding to Trump-era steel tariffs and
Chinese Lithuania sanctions. ACI targets third country actions impairing EU
sovereign policy choices through trade investment levers. Eligible victims
encompass member states institutions or EU-aligned third countries suffering
economic harm.
The instrument lists 14 countermeasures including tariff
quotas public procurement exclusions exceeding €5 million thresholds services
restrictions and foreign direct investment screening. As reported by Financial
Times trade editor Sam Fleming, qualified majority voting circumvents unanimity
blocking prior fragmented responses.
Activation procedure timelines commission council
coordination
Commission initiates investigation within two weeks of
notification determining coercion existence after four-month maximum probe.
Council assesses findings within eight-ten weeks approving by qualified
majority 55 percent states representing 65 percent population. Provisional
measures apply immediately pending full adoption entering force within three
months.
Suspension mirrors activation ensuring reversibility
post-resolution. As reported by Politico Europe staff, 2025 simulation
exercises tested Greenland scenario confirming 30-45 day rapid deployment
capacity against tariff coercion.

commentary
Theresa Fallon addressed EU-US economic linkages. Theresa
Fallon said in X post,
“What a break with Europe will mean for the US
economy. It remains to be seen if the EU’s Anti-Coercion instrument, created
during Trump 1.0, will be used amidst calls from some EU Member States for the
EU Commission to respond to Trump’s new tariffs with the trade bazooka. The
graphs below show the economic interconnectedness in the transatlantic space,
add to this reliance on the US for security. Trump is also pushing on the
perennial European sensitivity of loss of elite status. While Greenland plays
out, war in Ukraine continues. ‘The economies of the U.S. and Europe are
intertwined. The European Union is the U.S.’s biggest trading partner—and
Europe is the largest source of foreign direct investment in the U.S., with
$3.6 trillion invested into the U.S. as of 2024. It goes the other way, too:
U.S. companies make a fortune selling software, financial products and oil
across the Atlantic.’ WSJ”
