Maj. Gen. Mohammad Ali Jafari who was addressing an IRGC commanders meeting on Tuesday, said that nation’s resistance against the US had rendered blunt its most cutting weapon in imposing its political will on the Islamic Republic of Iran; “the US once sought to change Iran’s behavior, now itself changes its own political behavior of the past and were forced to forget the options on the table and to prefer a diplomatic option and solution for nuclear issue,” he added.
