Following Under Secretary Elbridge Colby’s remarks at NATO, Cato senior fellow Katherine Thompson backs his call for the alliance to return to its founding principles with concrete commitments: 5% defense spending, Europe assuming primary responsibility for conventional defense, and strategic discipline over vague promises.

Thompson calls for ending post-Cold War complacency and embracing a NATO 3.0 grounded in clear expectations and accountability for European allies.

Katherine Thompson is available for interviews on NATO reform and transatlantic security. Please contact Madison: mmiller@​cato.​org.
