NATO chief Jens Stoltenberg has played down fears that the reelection of former U.S. President Donald Trump would weaken the defense alliance as it works to ensure robust support for Ukraine. Stoltenberg said he did not think a second Trump presidency would jeopardize U.S. membership in NATO. "I believe that the United States will continue to be a staunch NATO ally, regardless of the outcome of the U.S. election, because it is in the U.S. interest," he said in an interview with CNN. Republican Trump, a fierce critic of NATO when he was president, repeatedly threatened to pull out of the alliance.
