US at 250: Internationalism vs. isolationism – America’s enduring foreign policy debate

27 May 2026, 5:00 pm – 6:00 pm

Location: Online / Chatham House, 10 St James's Square, London SW1Y 4LE

Think tank: Chatham House

This event hosted by UK think tank Chatham House explores the competing ideas shaping American foreign policy.

Since gaining independence, America’s relationship with global partners and its role in the international order have changed to meet the evolving geopolitical landscape and America’s strategic objectives abroad.

From Washington’s warning against entangling alliances and Wilson’s failed bid to reshape world order, to Roosevelt’s reluctant march into World War Two and contemporary doubts about longstanding alliances, the push‑and‑pull between internationalism and isolationism has defined American statecraft.

President Trump’s America First policies are designed to redraw Washington’s relationship with its allies, international institutions and the rules-based order to place American interests first.

This session, part of a series of events dedicated to the 250th anniversary of America’s founding, asks whether today’s scepticism towards the international order marks a historic rupture or the latest swing of a familiar pendulum.
