JFK. Everyone misses that's what his version(and Garrison's) boil down to, a reason I can't believe it's an acclaimed film.
http://en.wikipedia.org/wiki/Iran The country has always been known to its own people as Iran; however, to the outside world, the official name of Iran from the 6th century BC until 1935 was Persia or similar foreign language translations (La Perse, Persien, Perzie, etc.).[8] In that year, Reza Shah asked the international community to call the country by the name "Iran". A few years later, some Persian scholars protested to the government that changing the name had separated the country from its past, so in 1949[8][9] Mohammad Reza Shah announced that both terms could officially be used interchangeably. Now both terms are common, but "Iran" is used mostly in the modern political context and "Persia" in a cultural and historical context.
