“Many people in the West don’t understand that there is nothing “natural” or ahistorical in the fact that Islamic fundamentalism is nowadays the most visible political current among Muslim peoples. They ignore or forget that the picture was completely different in other historical periods of our contemporary history – that, for instance, a few decades ago the largest nongoverning communist party in the world, a party officially referring therefore to an atheistic doctrine, was in the country with the largest Muslim population: Indonesia – of course, until the party was crushed in a bloodbath at the hands of the US-backed Indonesian military starting in 1965. They ignore or forget, to give another example of the same kind, that in the late 1950s and early 1960s, the most massive political organization in Iraq, especially among the Shiites in Southern Iraq, was not led by some cleric but was here, too, the Communist Party”
—Gilbert Achcar and Noam Chomsky, 2007

Yes. true. However, for most Westerners that was irrelevant because "communism" was anti-Western, and thus Muslims, whether in Iraq or Indonesia, made bad choices (another 'fundamentalist' choice!) during the so-called Cold War.
