"If that is the end game of American policy, I would be tempted to become an isolationist. America just can't handle the moral burden, and should stay the hell out of foreign adventures that are other than directly related to ending states that attack us, de jure or de facto, ala Afghanistan."
It is the end game.
Remember: isolationism does not work unless we abandon Israel.
No Israel, no US tensions in the Middle East. Muslims are not blowing up the Chinese.
Abandoning Israel is immoral too.
In for a penny, in for a pound.
One other little matter. Your policy might cause a regime change in Saudi Arabia, and cause it to become a fanatical anti American state, and a host of terrorist perps. I guess we would need to send in the troops there. How large an increase are you proposing for the American army, and how will we secure the "surge" of additional bodies? Doubling or tripling the pay, or the draft, or what? The military other than the airplane and boat services, can barely meet their quotas now. Not to put too fine a point on it, it (your policy) is all quite insane. In any event, insane or not, it won't happen, so maybe getting real, do you have an opinion about the Plan B issue that I posed to jervitas, who has taken a break, apparently?
Even abandoning Israel wouldn't work. Muslims see the US as the fount of everything they hate. They have to turn us into an Islamic hellhole. As long as the US exists as a free country, we're the hope of salvation for everyone else.
