However, Aradalan did mention that her grandmother did not live to see the 1979 revolution or the US embassy takeover.
Given the context of the times (near daily threats of US or Israeli attacks on Iran), the fact that the 1953 coup became the boilerplate for other bloody CIA coups (esp. Guatemala and Chile), and the obvious blowback of destabilization, tyranny and war that the 1953 coup continues to produce, you might think that some mention of it would come into the essay. It's an obvious chance to educate an American audience that continues to be ill-informed about Iran. Also, on a personal level I wondered "What did her grandmother think of the coup?" and "Was she involved in any way?" etc.
And that is precisely the point. Nothing. 1953? What 1953? Instead, talk about selfless Americans bringing the light of civilization to the backward Iranians in the 1950s and be sure to mention those radicals of the 1979 Revolution and the US Embassy takeover. Leave the audience with all their prejudices reinforced and their ignorance intact. When that is the goal, NPR is pretty darn effective.
