There are many things that Americans can do to be supportive of the Iranian desire for reform and freedom. Having our government actively take a role in deciding the outcome of their election is NOT one of those things.
The U.S. should limit its involvement to facilitating Iranian communication via available technology (as they have done, so far), calling on the Iranian leadership to use peaceful means to handle protests, and stating clearly that the Iranians deserve an election that is not fraudulent.
Going beyond that point will do harm to this process.
Um ya:Given your logic, it would be ok for China to meddle with the U.S. government because they trade with us.

But regardless the U.S. would never nationalize Chinese assets or renege on Chinese debt in the first place, and if we did I'm sure they would use every bit of influence at their disposal to stop us, and justly so.
You all are missing the point, "meddleing" is good IF there is a rock solid PLAN that all or most agree will serve a good purpose. We meddled in Viet Nam and Afghanistan when the Russians were there and now look. We meddled in Iraq and it may turn out OK. So, like any endeavor make damn sure you are weel schooled and willing to handle the load.
Think if Trump get elected how much resistance he will face with in all phases of our country from people to military to politicians. He must not win.

After WW2 the Soviets refused to withdrawal from Northern Iran and propped up proxy communist agent provocateurs who didn't leave with the Soviets after they were forced to withdrawal under threat of a nuclear counter by Truman.
