Recall your Goebbels? I think these folks do.
The most brilliant propagandist technique will yield no success unless one fundamental principle is borne in mind constantly - it must confine itself to a few points and repeat them over and over.

In this case, they're going for sympathy. Making Beirut look like it's been laid waste to is part of the plan.
Goebbels would have loved to have had today's media back when he was running German propaganda.
But the doctored photo doesn't make Beirut look any more wasted than the original. That's my point. I understand propaganda. I know how it works, and how it can be abrupt or subtle. This case is neither. It's just stupid.
