We are now in the fifth month of supporting the rebels in Libya, and the fighting and bombing continues with no end in sight. Recall that on March 18 President Obama assured Congress that American involvement in Libya would be a matter of "days, not weeks", yet five months later we are still supplying substantial and expensive support (fuel, munitions, logistics, intelligence, air refueling, etc) to NATO forces.
Recall also that then-Secretary Gates and several of his top generals warned the administration in public that this would not be so easy, but were pointedly ignored by the White House. That "days, not weeks" estimate by Obama looks pretty naïve now.
