Chickenhawk.

You can easily substitute "Putz" for "Jonah Goldberg" in this classic:

As for the term chickenhawk, it isn't propaganda, it's what we call an "insult." There's no requirement for war supporters to enlist, any more than those who support tax increases needed to mail extra money to the federal government. Iraq chickenhawks are those who support the war, speak of the conflict in existential terms and describe support or opposition of that war in terms of "bravery" or "cowardice" while obsessing about 300/Lord of the Rings War porn even though there isn't the slightest chance in hell they'd sign up. Jonah Goldberg isn't a chickenhawk because he didn't sign up, he's a chickenhawk because there was never any chance that he would. It's an insult, and it's an effective one, because they know it's true.

Wait for it...

Indeed.
