Now, the president’s repeatedly stated desire to withdraw from NATO is raising new worries among national security officials amid growing concern about Mr. Trump’s efforts to keep his
meetings with Mr. Putin secret from even his own aides, and
an F.B.I. investigation into the administration’s Russia ties.
A move to withdraw from the alliance, in place since 1949, “would be one of the most damaging things that any president could do to U.S. interests,” said Michèle A. Flournoy, an under secretary of defense under President Barack Obama.
“It would destroy 70-plus years of painstaking work across multiple administrations, Republican and Democratic, to create perhaps the most powerful and advantageous alliance in history,” Ms. Flournoy said in an interview. “And it would be the wildest success that Vladimir Putin could dream of.”
Retired Adm. James G. Stavridis, the former supreme allied commander of NATO, said an American withdrawal from the alliance would be “a geopolitical mistake of epic proportion.”
