Iran was once one of the most developed countries in Asia, only behind Japan, Israel and the Soviet Union.
Developed in what sense?. There were plenty of issues with Iranian economy and development specially after the 1950's were all nationalizations were reversed.
Also I wouldn't include Israel on any of this comparisons since they were and still mostly pumped up by the West. Should aid and favorable deals be halted, they will quickly crash out.
The Shah was disregarding traditional culture and religion
The Shah was a despotic anticommunist moron just as smart as Nicholas II and proped up by the West which people were really wary of again, thanks to the coup. While they were modernizing and such, the economy was facing 30% inflation rate and thats despite having open access to western markets unlike the current Iran.
His modernization efforts also completely failed in that it didn't create the needed jobs and his land reforms displaced poor and smaller farmers in favor of his buddies and large foreign corporations. It also failed in that the Iranian economy was still oil-dependant and the 70's oil crisis really fucked them up because of this.
Like I said, people don't do revolutions for fun or just out of ideological things if there isn't a credible material crisis and interests underpining all of it.
