Yes, indeed.  Putin should be embarrassed.  

When you listen to the audiotapes, you become keenly aware that the pro-Russian separatists in the Ukraine are total boobs… or, as Josh Marshall writes:

The audio tapes posted by The New York Times might as well be from some future Russia-based version of Waiting for Guffman or Best in Show, a comical rendering of rustics and morons stumbling into an event of vast carnage and international consequence mainly because they're hotheads and idiots – the kind of people no one in their right minds would give world class weaponry to. It's like finding some white supremacist/militia types on their little compound in the inter-Mountain west and giving them world class missile launchers and heavy armaments.

This is a f'-up on Putin's part of almost mind-boggling proportions. Yes, a tragedy. Yes, perhaps an atrocity. But almost more threatening, a screw up. Malign intent is one thing. So is aggression. But goofs of this magnitude by someone who controls a massive military arsenal and nuclear weapons are in a way more threatening.
