Sense our government is so worried about iran why don't they help the people to overthrow there government?

no i am not talking about another war . but there must be something that we can do to help the ppl of iran . to overthrow there government . we are trying to talk the Iranian out of making weapons of mass destructing . but that is never going to happing . there minds are made up and there is nothing anyone can say that is going to change the mind of the iranian gov. there going to do what ever they want to do . there are two options that our gov. has one. go to war with iran i think we can all agree that is not a good ideal . option no. two support the iranian ppl help them overthrow there gov. i would say that option two is the best Choice for america . this can be done without going to war with iran . and i do believe that the iranian ppl wants our help . and need our help . all the talking is not going to do any good our gov. is wasting there time . trying to talk iran out of making weapons of mass destruction is never going to work . the ppl of iran has not giving up on trying to overthrow there gov. there were new anti government protest in iran . thousands of iranians went to the streets again . to protest there gov. of course you can guess how that went . it didn't go well at all . but the fact that the ppl are still going to the streets to protest there gov. shows how much the iranian ppl wants freedom . i just don't understand why our gov. wont support the ppl of iran .
