This telling quotation you're about to read from Markos Moulitsas Zúniga of the Daily Kos is worth reading and analyzing because it exposes some of the underlying ideological beliefs that make today's liberals incapable of handling foreign policy. From Kos...
"Here's the deal -- a war is worth fighting if you would sacrifice everything you hold dear to fight it.
A war is not worth fighting, if you'd rather maintain your cushy lifestyle and let others do the dying for you, let other families lose their mothers and fathers and spouses and children.
It's that simple. The 101st Fighting Keyboarded and their bretheren in the Republican Corporate Media fail this very easy test of the sincerity of their convictions."
On the surface, this would simply seem to be a combination of the chickenhawk "argument" (and I used the word "argument" very loosely here) and Michael Moore's "would (you) sacrifice your child to secure Fallujah" comment to Bill O'Reilly and hence, is rather silly.
If you wanted to be as ridiculous as the people who take those sorts of positions, you could just as easily say that if you're serious about preventing war, then you should go to Iraq and be a human shield for Al-Zarqawi. You could also apply that sort of shallow "reasoning" to firemen or policemen just as easily as it can be applied to soldiers...
"Oh, well if you're not willing to charge into a burning building to try to put out a fire, then you shouldn't expect a fireman to do it. Same goes for cops. How can you ask a policeman to risk his life enforcing the law if you're not willing to grab a shotgun, kick in the door of a crackhouse, and start making citizens arrests?"
The rest is just as good.
