The brightest image of the past two weeks was the scene of displaced families returning home; more than a thousand families are back to their homes under the protection of the Army and police. This figure invites hope that Baghdad will restore its social, ethnic and religious mosaic.

Marketplaces are seeing more activity and stores that were long shuttered are reopening--including even some liquor stores that came under vicious attacks in the past. This is a sign that extremists no longer can intimidate people and hold the city hostage. All of this gives the sense that law is being imposed.

Checkpoints are not seen as scary threats to the innocent. They look more professional and impartial as they include members of the police, army, multinational forces and even traffic cops with laptops verifying registration papers. We've lost the fear that checkpoints might be traps set by death squads; they search everyone, even official convoys and ambulances.

We feel safer about moving in the city now, and politicians who used to hide behind the walls of the Green Zone are venturing out. Watching Mr. Maliki walking on Palestine Street in central Baghdad gave a positive impression that the state, and not the gangs, owns the streets.
