The Wall Street Journal has the latest on Iraq's political situation: "Nouri al-Maliki performed a belated service to his country Thursday by resigning as Prime Minister. His decision spares Iraq from a crippling and potentially violent confrontation with his anointed successor, Haider al-Abadi, and offers Baghdad a fresh chance to confront the jihadist insurgency. It also removes President Obama's main excuse for failing to come to Iraq's aid. ... The apparent resolution of the political crisis should allow the new government to begin reclaiming the ground it has lost to the jihadists. But those terrorists—and the caliphate they claim to have established—also pose a direct and intolerable threat to the United States. A serious American policy would demonstrate to the new Iraqi Prime Minister that we are, after all, a dependable partner willing to put the full weight of our power in the service of a common interest. With Mr. Maliki gone, so too goes Mr. Obama's alibi for unseriousness."
