In the early years of World Wars I and II, Europeans implored us to come save them from the Germans. We did. In the early Cold War, Europeans welcomed returning GIs who stood guard in the Fulda Gap. Now, with the threat gone, the gratitude is gone. Now, with their welfare states eating up their wealth, their peoples aging, their cities filling up with militant migrants, they want America to continue defending them, as they sit in moral judgment on how we go about it.
"...as they sit in moral judgment on how we go about it."
I do find it preposterous that Europeans actually believe they are somehow morally superior to us. Exactly what moral basis would that be...?
