Instapundit makes the following prediction:
If Barack Obama is elected President, he'll be far more warlike than President Bush, and far more warlike than his pre-election rhetoric suggests. Because before he's elected President, attacks on America are just attacks on America. But after he's elected President, attacks on America will also be attacks on Barack Obama.
I think he's right, and there's a further consideration.
Because Barack Obama lives in a fairy world of fluffy clouds and rainbows, he will be most terribly, personally offended when our enemies don't get with the program.
In order not to appear weak (after all, it's all about appearances) he'll respond to any attack with either 1) ineffective, or 2) genocidal rage.
