Trump's Shift on NATO: What Europe Must Do to Stand Alone
In a controversial shift, Trump suggests Europe must take on NATO defense, raising questions about alliances.
March 7, 2025, 5:52 a.m. ET - President Donald Trump has long expressed skepticism about the NATO alliance, emphasizing that many member countries rely heavily on American support. During his initial tenure, he even entertained the idea of the U.S. withdrawing from this collective defense pact. Now, as he enters a second term, the message is clear: the security of Europe is no longer the U.S. priority, with a greater focus on domestic borders and countering China in the Indo-Pacific.
Recently, Trump remarked that the United States might only protect NATO allies that contribute sufficiently to their defense budgets. He labeled this stance as “common sense.” This raises significant questions regarding the future of NATO and what European nations would need to undertake if they lose the extensive American support they currently have.
To foster a robust European defense mechanism, former NATO ambassador Ivo Daalder suggests that Europe will need to enhance funding, increase troop numbers, and improve cooperation with Washington. He points out that NATO was originally structured around American leadership, making it heavily reliant on U.S. military capabilities, intelligence, and logistics. The architecture of NATO is predominantly influenced by the United States, which has historically operated the command structure.
Daalder warns that if the U.S. were to withdraw its military presence, it would create a vacuum that could undermine the alliance's integrity and effectiveness. He remarks, "The United States is the linchpin of the alliance; if you suddenly pull out the skeleton, the body dies."
The dynamics within NATO could drastically change if European nations do not step up, prompting a necessary reevaluation of resources, strategies, and commitments to ensure their security without American backing.
