You speak! So too shall I.

My point is that Iran has been conquered before, and it will be conquered again. The willful nationalistic conscription seen is not the same thing as guerillas hiding in the population in an insurgency, it's the untrained population joining the regular forces. We usually call these people "soldiers" and not "meatshields".

Regardless of whether or not a percentage of the population joined the military, it really wouldn't matter in the engagement I envision because they would be denied centralized leadership, have no visible enemy to fight, and have no infrastructure.

Government officials tomahawked in the night as they sleep, no power stations, no bridges, no government buildings used for public services. Drop a GBU-39 on any gatherings of armed men or armor, let AGM-88s take out any remaining radio transmissions. That leaves them with no means of leadership or retaliation against an enemy which has no fog of war war(thanks Keyhole and NROL-39!).

It'd be over in a day. Raytheon's stock price would soar, Iran would be rubble, and the middle east would still hate us.
