American airstrikes...create risks, especially if our intelligence there is rusty. The crucial step, and the one we should apply diplomatic pressure to try to achieve, is for Maliki to step back and share power with Sunnis while accepting decentralization of government. If Maliki does all that, it may still be possible to save Iraq. Without that, airstrikes would be a further waste in a land in which we've already squandered far, far too much.
