Andrew, before we all get carried away with these Krushchev/Ahmadinejad comparisons, it’s worth remembering what the Commies didn’t do. The Soviets didn’t seize foreign embassies in Moscow and hold its diplomats hostage. The Soviet leadership didn’t publicly announce death sentences and multi-million-dollar bounties on foreign nationals. Even at the height of the Cold War, the USSR maintained the minimal courtesies between sovereign states.
The Islamic Republic of Iran does not and never has. For 28 years it has been in sustained, intentional breach of Article (d) of the Montevideo Convention on the Rights And Duties of Sovereign States – ie, “the capacity to enter into relations with the other states”. The US, of all nations, has no interest in allowing a gangster to pass himself off as just a regular member of the club.
Also: Krushchev was taken to see Frank Sinatra and Shirley MacLaine on the set of Can-Can and pronounced it “decadent”. I’m not sure what the equivalent would be today, but there must have been some or other gay sitcom the old sodomite-beheader could have been schlepped along to.
