Security Wall?

By the way, do any of you remember the 'security wall' that was announced with great fanfare back in September? I do, dimly now, and I occasionally wonder what progress has been made, or if that strategy has been abandoned.

"The enemy is changing tactics, and we're adapting," President Bush said Friday in Washington. "The enemy moves, and we will help the Iraqis move. And so they're building a berm around the city to make it harder for people to come in with explosive devices, for example. . . . They got a clear-build-and-hold strategy."

Would someone ask The Decider?
