What the hell are you guys talking about?
The question is "Would you sacrifice your kid for Falujiah?"
(and comparison to rik's variation, "Would you sacrifice your kid for a bridge in Germany?")
What this has to do with cherry-picking orders is beyond me. It has to do with whether it is worth sending American soldiers to war for this issue.
For example:
"Defeating an invading force" is obviously something that I would be willing to have my loved ones in the military die for. I would sacrifice a kid to protect America from an invasion. OTOH, "Changing the carpet styles in the Kremlin" is not something I would want or be willing to have my loved ones die for.
Therefore, I would support a commander-in-chief who sent troops, including my kin, to stop the first scenerio. I would not support a commander-in-chief who did the second.
In the same way, "Would I sacrifice my kid to protect a bridge in Germany?" Yes. I support sending forces to carry out such acts.
"Would I sacrifice my kid for Falujiah?" No, it's not worth the cost.
It has nothing to do with following orders. It has to do with which order the commander-in-chief is giving. Does the benefit to be gained justify the cost? When it's other people's kids, it's easy to say yes. But when it is your own? If you can say yes then, you know it is a cause worth fighting for.
