Krugman on Austerity, Germany's and Ours

Dr K is in Teuton territory, listening to the deficit hawks.

What’s the economic logic behind the [German] government’s moves? The answer, as far as I can tell, is that there isn’t any. Press German officials to explain why they need to impose austerity on a depressed economy, and you get rationales that don’t add up. Point this out, and they come up with different rationales, which also don’t add up. Arguing with German deficit hawks feels more than a bit like arguing with U.S. Iraq hawks back in 2002: They know what they want to do, and every time you refute one argument, they just come up with another.
