What "military" option would gain the most support from outside Iran, give max boost to the people in the streets protesting, and cause the most harm to the Regime without hurting the People?
My thought would to be 1) go after the cash cow of the regime...which is probably its sales of Oil and Gas. 2) Decapitate the leadership that is responsible for internal security. 3) install yet more economic sanctions on senior members of the Regime and seek out and seize any external holdings they have. Whatever done should not harm the people on the streets but do massive harm to the select few that are benefitting from their ill-gotten Gains.
