By Definition

This is pretty much the definition of guerrilla warfare/terrorism, isn't it? Chaos as an Anti-U.S. Strategy

The bombing of the United Nations headquarters in Baghdad today provided grisly evidence of a new strategy by anti-American forces to depict the United States as unable to guarantee public order, as well as to frighten away relief organizations rebuilding Iraq.

Nothing new, per se, in the grand scheme of things. The whole point of guerrilla-style tactics, especially against an occupying force, is to cause trouble because direct military confrontation won't work.
