The liberal NY Times:
There is no perfect formula for military intervention. It must be used sparingly — not in Bahrain or Yemen, even though we condemn the violence against protesters in both countries. Libya is a specific case: Muammar el-Qaddafi is erratic, widely reviled, armed with mustard gas and has a history of supporting terrorism. If he is allowed to crush the opposition, it would chill pro-democracy movements across the Arab world.
