Let me flip the question back at you.....
Do you think that what America has gotten or will get in Europe is worth the price paid (WWI, WWII and the Cold War), in dollars and lives ??
They'll have had a 100 year renewal due to our boys' blood, when they finally die off enough by 2050 to no longer be "european" and are taken over by their immigrant population.
100 years is a good, long stretch of stability & no major wars. Expecting solutions to last in perpetuity is not realistic.
Well, if this is a "show everyone what we can do to countries that support/harbor terrorists" operation, we could have just blasted them to heck and went home
This is what we ought to have done, with the added proviso that we ensured Saddam was killed in the carnage.
And that is what I would have desired: carnage. All this "surgical strike so we don't tip over their teacups or scorch their mosques" baloney would have been out the door.
It would have been an object lesson to future potential antagonists: yank our tail and we will turn around and rip out your throat.
Expecting democracy and decent behavior from savages that have no tradition of civilized behavior is like expecting Muscovy ducks to lay eggs that hatch swans.
