Gee. Lots of people to see him in Germany. See. Wasn't it not too long ago Sen. McCain was criticizing Sen. Obama for not having the foreign policy cred and that he hadn't been to the Middle East in a dog's age? I think this falls squarely in the category of be careful how you challenge a man who can, you know, step up.
I'm of the mind that Obama is not particularly afraid of anything. Not McCain. Not Bush. Not Cheney. Not the GOP. The advantage of not having a gazillion years already lived or multiple served terms in Congress, is that there is not a lot of political equity that he could not stand losing. Their criticism that he is a relative (to the above old guys) neophyte could have held traction if Obama was stupid or entrenched in his own political capital. He's not. He fears nothing, which is driving the Axis of Empty to distraction. Those guys have rarely had to deal with thems that don't take a knee.
