There is a great point that needs to be made that I haven't seen made by many in the mainstream (for obvious reasons).
Israel and their supporters want "regime change" in Iran, yet the person they hint at wanting is the son of the former absolute dictator monarch, whose security forces (SAVAK) were despised and in the end (it is alleged) simply became the Islamic Republic of Iran's current "secret police".
What difference, if any, will that make?
Where is the "democracy", "women, life, freedom" in that?
The last free and independent Iranian state was led by Mohammad Mosaddegh. He was overthrown because he wanted to nationalize the Iranian energy sector. His overthrow in the end helped to catalyze the 1979 Revolution. This is why the U.S. administration apologized in 2013, because the whole thing "blowback"ed in their face.
People will say "Mosaddegh was himself a dictator!!!", even though this claim is only partially true at best.
He was elected, and was very popular with the people. He was forced out by the conservative Shah but then reinstated when the Shah realized that he was simply too well-liked.
He was secular, leftwing, even liberal, and not a religious fundamentalist. He was attacked by the Shia fundamentalists (future Khameneists) for being a "Communist" (irony).
He assumed "dictatorial powers" in order to push through his policies that actually favored the Iranian people. This is what led to the coup against him (sponsored by the U.S. and Britain).
This coup brought the repressive dictatorial Sha to power, whose repression led to the 1979 Revolution which led to what we see today.
Every horror that Iran has inflicted upon the Middle East and every horror that has been inflicted upon them could have been prevented if, in the 1950's, democracy was given a chance in Iran.
