Zack Polanski calls for reassessment of UK defense ties with the United States amid transatlantic tensions over Greenland and NATO cooperation
Zack Polanski, leader of the Green Party of England and Wales, has urged the United Kingdom to reassess its long-standing defence relationship with the United States, including consideration of removing U.S. military forces from British bases.
Speaking in the context of escalating diplomatic tension between London and Washington, particularly over U.S. tariff threats and President
Donald Trump’s assertive foreign policy posture, Polanski argued that the UK should reduce its reliance on American military cooperation and undertake a “genuine strategic defence review.” Polanski’s remarks came as part of a broader critique of current security arrangements and his call for Britain to recalibrate its alliances.
He suggested explicitly that the government should review the presence of U.S. forces stationed on British soil and explore options for their removal, a proposal he linked to his belief that the UK’s security policy is overly dependent on the United States and vulnerable to changes in U.S. political leadership.
The Green Party leader also reiterated his view that the United Kingdom should reconsider its membership in the North Atlantic Treaty Organization and decrease defence procurement from U.S. arms manufacturers, as part of a wider shift toward strategic independence.
He said that reviewing U.S. military bases should be undertaken even if such a review would require the UK to bolster its own defence capabilities or build new partnerships.
Polanski’s comments reflect a minority but vocal strand of British political debate that sees traditional transatlantic security ties as outdated and in need of fundamental change, especially in light of contentious issues such as President Trump’s Greenland proposals and his administration’s tariff threats against key European allies.
The prime minister has sought to maintain strong diplomatic relations with Washington, but Polanski criticised this approach as excessively deferential to U.S. interests and called for more autonomous British decision-making on defence and security matters.
Polanski framed his proposals as part of a broader push for peace, arguing that unilateral steps towards reducing reliance on the United States could pave the way for alternative frameworks of international cooperation focused on diplomacy and disarmament.
His remarks have sparked debate across Westminster, with supporters of continued close defence cooperation maintaining that shared security commitments underpin collective defence, while critics of Polanski’s stance argue that weakening ties could undermine both national and European security.
