BRUSSELS – Russian President Vladimir Putin may not be planning an imminent assault on NATO nations, but the United States says its military allies need to train and invest like he is, so they’re ready to fend off a sudden attack.
After leaked U.S. intelligence reportedly revealed that Russia could launch a limited assault, such as a land incursion or cyberattack, on a member country within the next few years, America’s allies have been on high alert.
The warning contradicted assessments that Putin would not attempt to draw NATO into a fight while he’s battling Ukraine – and came amid concerns about a U.S. weapons shortage, as the Trump administration wages war on Iran.
In an exclusive interview with USA TODAY at the military alliance’s headquarters in Brussels, U.S. Ambassador to NATO Matt Whitaker declined to comment directly on the leaked intelligence, while stressing a need for allies to be vigilant in their defense spending and weapons production.
“You can't predict what Vladimir Putin's going to do or any adversary. All you can do is be prepared for it and deter and make it not worth their time to make that move,” Whitaker said. “And I think we are preparing every single day to prevent that from happening, and if it does happen, to be ready for it.
“We should know that our adversary invaded Ukraine, and so we should all be pretty clear-eyed,” Whitaker added.
