The United States Military can and probably will apply incredible force on this regime if it continues to side against liberty. That's the key here. If the regime in Iran were to surrender its despotism, free its political prisoners, end its support of terrorism and stop threatening the community of nations with clandestine nuclear weapons programs and oil embargoes the free world would most likely back off.
I know.... unlikely it may be, but it could happen.
The Iranian regime needs to surrender.
