In 1953, the CIA orchestrated a coup d’etat in Iran that ousted a democratically elected premier and restored a religious extremist dictator shah to power.

Correct (or partly correct - the Shah was secular) but has little to do with Israel, and nothing to do with Arabs?

Meanwhile, the Zionist movement has been supported by western countries since its founding.

Only in the broadest sense? Israel's foundation was only enabled by Soviet military aid at a time when Western countries were largely unwilling to assist; the US intervened in support of Egypt against Israel in the 1950s, and US military aid didn't become a major factor in Israel until the 1970s.

In addition to US and European countries, the Saudi royal family and OPEC countries have been doing all sorts of fuckery, with the support of western countries and especially western oil companies.

... that was also not until the 1970s.

This is more complicated than “Isreal strong” and “Arab bad.”

It's less "Israel strong" and more "Dictatorships hollow out institutions, including vital institutions like the military", like I explicitly said.

So are you saying Western involvement helped create the dictatorships in Arab countries? If that’s the case, how did it happen, and why does the Arab world have such strong resentment toward the West?
