It looks the White House expects the surge to continue on indefinitely -- Bush is demanding another $50 billion for his Iraq policy:

The request is being prepared now in the belief that Congress will be unlikely to balk so soon after hearing [David Petraeus and Ryan Crocker] argue that there are promising developments in Iraq but that they need more time to solidify the progress they have made, a congressional aide said.

As Kevin Drum put it, "So that's that, I guess. The White House already knows what Petraeus and Crocker are going to say and they figure it's going to be $50 billion of good news. And with that, the Kabuki show continues."
