Reaping the whirlwind
More than 11 years of grinding, terrible (if low-intensity) war.
There can be no clearer evidence of failure than this. There can be no more obvious indictment of the failures of the last decade to build a better world. There can be no stronger repudiation of the Wilsonian doctrine of an aggressive, democracy-promoting foreign policy. When America adopted such arrant libprog nonsense as its official foreign policy in the early 20th Century, it left behind the great wisdom of the Monroe Doctrine and did, indeed, go abroad in search of monsters to slay.
