This is a good article. Josh Marshall has been cautious about making direct accusations. But this article is strong and direct.

Whether Vladimir Putin has something on Donald Trump or somehow has him in his pay hardly matters. If he doesn’t, he apparently doesn’t need to do since Trump insists on doing more or less exactly what Putin would want of him entirely on his own. Does this sound hyperbolic. Yes, it absolutely does. I’m even surprised I’m writing it. But look at the evidence before us. A simple statement on a decades old security commitment is the simplest, most pro-forma thing to do. And yet he refuses. Again and again.
Something is very wrong here. But we don’t know yet its origins or where it’s taking us.
