THE spectacle of American, British and French missiles pulverising an Arab and Muslim country at the dead of night arouses a sense of foreboding. Such ventures have too often begun with good intentions and naive overconfidence, as oil-rich despots see their armour crumple and burn beneath superior Western technology. Within weeks, though, vainglory turns into a costly and bloody quagmire. Yet nobody could accuse Barack Obama and his allies, chiefly Britain’s David Cameron and France’s Nicolas Sarkozy, of overconfidence in attacking Libya on March 19th. It is hard to think of a military enterprise that has been conceived in so much doubt and anxiety. What if Muammar Qaddafi sits out the raids in his bunker? What if Libya is partitioned? What if, chastened by news footage of dead women and children in a Tripoli market, the coalition starts to fall apart? What if many of the eastern Libyans whom the outside world is protecting turn out to sympathise with al-Qaeda? What if they go on to behave as murderously as the colonel and his paid killers?
