Eighteen members of NATO will spend at least 2% of GDP on defense, the security bloc’s top official revealed amid renewed anxiety about the U.S. commitment to the trans-Atlantic alliance.

“That is another record number, and a sixfold increase from 2014, when only three Allies met the target,” NATO Secretary-General Jens Stoltenberg announced Wednesday. “In 2024, NATO Allies in Europe will invest a combined total of $380 billion in defense. For the first time, this amounts to 2% of their combined GDP.”
