Of course, had Barry supported the freedom movement there a few years ago MAYBE the mullah's wouldn't be in power anymore. If that had happened, the Iranians could then tell the Russia's to go F*** themselves.
It probably wouldn't taken that much support from the Obama regime, when the freedom movement was at its peak (not like invading or anything). The mullah's were super weak then, and the Iranians people themselves (who were fairly pro-western) would have done the majority of the work of toppling them. But we know what happened, a waffling Barry did nothing.
I think Iranians best hope for regime change may be an Israeli military strike against nuclear sites. A well timed and placed strike could make the mullah's regime very wobbly again. Maybe at that point, if the freedom movement hasn't been completely destroyed, could take advantage of it. Remember, before 1979 Iran and Israel were friendly. Even though most are Muslim, Iranian's aren't Arabs, but Persians.
