I don't think we want to be in too many places at once.
Us pulling out of Germany was getting ready for something else as well IMO.
Iranians need to receive a message like the one that should have been sent to the German people in 1939: You are either part of the solution or you are part of the problem. You must take care of this government before we/others have to. When the missles fire and the tanks role it will be too late to discriminate between those in Iran who supported the regime and those who opposed it.
