Iran's attacks are certainly puzzling. I don't dare to draw any conclusions. There is evidence of both military weaknesses and treacherous follow-ups.
I'd like to think that, like the military braggers of sadan Hussein, who to the very end tried to show the world they were defeating the invaders while the American troops were controlling the e main cities, the Iranians are equally propagandistic.
However, terrorist groups in the middle East have a history of cowardly warfare.
They will attack from and when the Americans least expect it.
