NATO Leaders Reaffirm Commitment to Collective Defence, Trump Pledges U.S. Will Stay in Alliance

Leaders of NATO member states have jointly reaffirmed their commitment to collective defence under Article 5 of the alliance's founding treaty, the provision that treats an attack on one member as an attack on all. U.S. President Donald Trump assured allied leaders that the United States intends to remain in NATO, offering reassurance amid longstanding questions about Washington's dedication to the transatlantic alliance. The joint declaration signals an effort by member states to present a unified front on the alliance's core security guarantees. Article 5, NATO's mutual defence clause, is widely considered the cornerstone of the alliance's deterrence posture, particularly in the context of Russia's ongoing war in Ukraine and heightened security concerns across Europe. Trump's pledge is significant given his repeated past criticism of NATO and suggestions that the U.S. might not automatically defend allies he deemed to be contributing insufficiently to their own defence budgets.
