The Montana native knows more than most about facing off with terrorists and the grim realities of war.

But as he has watched bloodthirsty Vladimir Putin's invasion of Ukraine from afar, he has seen soldiers dying for a leader who's 'lost his marbles' with an endgame to cement his place in the history books, and has witnesses the U.S. responding with what he perceives as weakness.

In an exclusive interview with DailyMail.com, the decorated veteran criticized the Biden administration for cancelling a nuclear missile test last weekend while Russian forces started to attack Ukrainian citizens and how the Pentagon is more concerned with their climate change agenda than trying to deter Putin.

'You don't defeat a crazy man with nuclear weapons, with weakness. It's like trying to stop a schoolyard bully by appeasing him, it's nonsense.
