You mean armed troops, I am sure we don't have enough! This is moving much too fast for us to do much else than stand on the sidelines and cheer and look at the blood and gore coming!!
Will the Iranian military kill Iranian students in the streets, if it came to that?
The US military need not become directly involved, at first blood. The fact that we have assets in the area is enough to strengthen the resolve of those who wish regime change. We do not know what the US has in the area, or in-country. This administration has not been one to blab and broadcast any covert support or operational capability. What you don't see is more important than what you do see.
