Rollback or Containment?

"Rather than assuming an offensive posture, the West should revert to a defensive one. Instead of attempting to impose its will on the Greater Middle East, it should erect barriers to protect itself from the violence emanating from that quarter. Such barriers will necessarily be imperfect, but they will produce greater security at a more affordable cost than is gained by engaging in futile, open-ended armed conflicts. Rather than vainly attempting to police or control, this revised strategy should seek to contain.
"Such an approach posits that, confronted with the responsibility to do so, the peoples of the Greater Middle East will prove better equipped to solve their problems than are policy makers back in Washington, London, or Paris. It rejects as presumptuous any claim that the West can untangle problems of vast historical and religious complexity to which Western folly contributed. It rests on this core principle: Do no (further) harm."

Andrew J. Bacevich in The Boston Globe argues that American and European leaders "have enmeshed the West in a war that it cannot win and should not perpetuate."
