"Our allies wonder if they will be compromised by Trump. They have to worry about sharing intelligence information."

That's already happening. The BBC has reported that British authorities are angered by U.S. intelligence leaks regarding the Manchester bombing and have already made the decision to stop sharing intelligence information with the U.S. Ponder that. Increasingly, the world's leaders will be working around the U.S. on a host of issues, and that should be worrisome to all.

Meanwhile, Trump's flip-flopping on NATO and everything else still doesn't seem to bother his unflappable base. Writing for The Root, Jason Johnson believes that Trump voters don't care about his flip-flopping. All they care about is that he drives liberals crazy, that he’s white and male, and doesn’t challenge Americans to grow up and change. He says of Trump, "He’s a political cudgel, a temper tantrum from an electorate that votes out of spite, not hope; anger, not ambition; disdain, not destiny."
