re: "We can't let this continue"
The administration is currently pushing on diplomatic fronts, not military ones. There has been progress in getting some serious action like sanctions, even from nations like France and Germany. We'll see what happens after the next Iran's current idiocy doesn't help their case.
The only people running around screaming about oncoming war are leftist psycho hose beasts like Hersh, based on his usual phantom sources.
Eric's little example speaks for itself.
The Democratic Party's complete lack of a rational alternative is pretty much par for the course, as it has been in most foreign policy situations.
