Taibbi's NY Press article on "National Security Democrats" is worth reading.
And, look, I agree with those who say that Democrats have an image problem on foreign policy. And, I agree with those who think that this image problem is to some degree based on an actual lack of foreign policy substance.
But, on foreign policy as with everything else, the "me too!" position gets you nowhere.
The Democrats who made it impossible for Democrats to have an articulate distinct position on foreign policy are the ones who pushed the party into supporting the Iraq war.
I don't actually disagree with the general proposition that the Democrats need a bit of piss and vinegar in their foreign policy, but they have to figure out where to aim that piss. Peter Beinart and Joe Biden and the rest of the gang didn't aim their piss, they let George Bush grab their dicks and point them towards Baghdad. And, now, two years later, they want to lecture the rest of us on how to be perceived as "strong."
The way to be perceived as strong isn't to let George W. Bush tell you where to point your dick.
