Following the U.S. withdrawal form Iraq, the questions, “What was that all about?” or, “What went wrong in Iraq?” or even, “Did something go wrong in Iraq?” (never mind, “What is going wrong in Afghanistan?”) don’t rise even to the level of conversation-enders. They don’t rise, period, not even among GOP presidential candidates, beyond the odd sound bite.

Famously, of course, Ron Paul calls for withdrawal of U.S. troops everywhere, a rollback of the international security force the U.S. military became after winning World War II.
