I noted earlier that the Washington Post seemed to miss the story and the dimensions of the wall being built by Multinational Forces.

The disparate illustrations are worth noting for the differences. The actual (red portion) of Quds Street where the barrier is being built is about 3.2 miles according to the US mapping agency. However, in The Washington Post misleading map the scale is completely wrong on a basic bit mapping: 7.5 miles. In addition, the 4 on the miles scale should be a 1. Since the misleading illustration makes the barrier appear 2.5 times longer than it really is, the project seems doomed. As the barrier has unfolded, and is much clearer now, the JAM (the Mahdi) is beatable, and now beaten down and cowed.
