Trump's NATO Exit Threat Targets a Shield That Has Protected Europe and America for Decades
President Donald Trump's threat to pull the United States out of NATO has alarmed allies because the alliance has spent decades protecting not only Europe but the United States as well. NATO countries have fought alongside American troops in multiple conflicts, invoked collective defense after the September 11 attacks and shared casualties in the name of common security. The danger in Trump's threat is not only diplomatic drama - it is the strategic opening it could create for adversaries that benefit when the West looks divided, uncertain and easier to intimidate.
