Toppling tyrants is ineffective in the long term without years of unpopular occupation.

Two and a half years ago, the U.S. pulled every soldier out of a mostly quiet Iraq. In the void thus created, formerly al-Qaeda-affiliated terrorists calling themselves “The Islamic State of Iraq and Syria” are now tearing apart the country, leaving medieval savagery in their wake.
Obama partisans are blaming the Bush administration for going into Iraq in the first place. But critics counter that Obama wanted out of Iraq before the 2012 election at all costs. The result of that reckless skedaddle is that we have thrown away the hard work of the 2007–08 surge that finally broke the back of both al-Qaeda and Iranian-backed Shiite terrorists.
