The USA toppled the Iran government and replaced with the dictator 'Shah'.
While the US (and UK) did help the overthrow of Mossadegh, this is quite a misleading formulation of it.
Mossadegh was quite controversial inside Iran and there was a lot of opposition to him. Yes, US and UK helped things along. But it's misleading to say that "USA toppled", as if it was a unilateral action. It is also misleading that Mossadegh was "replaced with the dictator 'Shah'".
Mohammad Reza Pahlavi was Shah from 1941 to 1979. Before that, his father Reza Shah reigned from 1925 to 1941. So no, Mosaddegh was not "replaced with the [...] Shah". He was replaced with another prime minister, Fazlollah Zahedi.
There were fears of oil being nationalized.
Not just nationalized, but also that foreign oil companies would not be compensated. Mossadegh was an ally of Moscow, btw.
He also did not govern democratically. He empowered himself to rule by decree, and in the 1952 elections he stopped the voting as soon as quorum was reached so opposition parties would not win seats.
An Iranian told me before that the people liked the USA.
I think a lot of Iranian people have liked the USA since 1953 too.
There was an American who died defending the Iranian democracy movent and was an Iranian hero.;
Who are you talking about?
Aft6er the revolution gaainst Shah the conservative clerics defeated the democracy supporters and seized control. The regime that exists today.
It shows just how dangerous it is to collaborate with the Islamists. Modern Western Left should be taking notes.
