My first reaction to the cessation of the most recent wall being built in Baghdad was that if President al Maliki asks the Iraqi and US militaries to stop building the wall, then we should stop building it.
But then I found out that other walls have been built in other sections of Baghdad with no similar outcry. In fact, they have been welcomed. These walls are not just solid slabs of concrete, but rather have at regular intervals gates through which access can be granted in a more controlled way. Terrorist acts can thus be severely diminished. The citizens of Amiriyah and Ghazaliyah had no problem with greater safety.
So why did the citizens of Adhamiyah? Well, it's not actually clear that they did. Leaflets passed around the area in the days leading up to the wall construction begin date threatened death to those who cooperate with Americans.
Iraq the Model sheds some interesting light on the issue of "The Wall":
Yesterday leaflets were distributed in the streets of Adhamiya (or Azamiya, English doesn’t have the exact sound anyway). The leaflets — printed and distributed by persons unknown — called on residents to protest the building of the wall. Knowing that the only organized entity capable of such quick response to events in Adhamiya are either the insurgents or al-Qaeda strongly indicates that they were behind the planned protest. More important still is that it indicates they see the wall as a threat to their movement and ability to carry out their actions.
Interestingly as well: Iraq the Model points out that Adhamiyah is not Sadr City, as the media reported...
