Plan B should be an enclave strategy. The United States should recognize that Iraq is turning into a country of enclaves and work to ensure that these regions stay as stable, terrorism-free and open as possible. The Kurdish enclave, bolstered by having captured the vital city of Kirkuk, is already a success story. The Shiite region of the south can be stable. It will be possible to work with countries such as Saudi Arabia and Jordan to influence the Sunni groups in the middle of the country, purging terrorists and empowering moderate Sunnis.
