Peter Wehner describes the conduct, but I think, when you behave as Obama as, the word “contemptible” can apply, with equal aptness, to the man himself (emphasis mine):
I have praised President Obama in the past for his decision to send more troops to Afghanistan. New facts have come to light since then. And, arguably, I should have better understood the true nature of the man in the Oval Office. Either way, the president, rather than distancing himself from the July 2011 draw-down date, has doubled down on it. He has said things in meetings and on the record that underscore his equivocation, his doubt, and his lack of fortitude when it comes to this war. And so it is fair, I think, to render a judgment I much rather would not: What President Obama is now doing – both escalating and undermining a war at the very same time — is not only unwise; it is contemptible. He has a constitutional duty and a moral obligation to choose one path or the other – to prosecute the war with commitment and resolve or to leave.
The president still has time, but not much.
