Trump says NATO 'failed,' US will act alone

White House Press Secretary Karoline Leavitt, in a public statement, declared that President Donald Trump has 'tested NATO and they failed.' She indicated the United States will continue its important mission independently, citing a lot of talk but very little action from the alliance. This public criticism signals a significant rift in U.S.-NATO relations under the Trump administration. The statement reflects the administration's unilateralist posture and frustration with perceived allied inaction.
