Lind says

William S. Lind's latest article on good news from Iraq includes a devasting critique of the U.S. strategy.

He argues that we are fighting the Sunnis on behalf of the Shiites, in apparent contradiction to our enmity with the Shiites Iranian allies. Thus every tactical success makes us strategically weaker.

Hey, I know how to fix it, Beaver. Let's fight the Shiites too!

Such a policy would be less contradictory, but not less stupid. Lind says that the Shiites would be able to cut off supply lines and communication, leading to operational defeat.
