I'm a 1956ist.
I'm a 1945ist; the Pacific War ended when nukes were used.
I could even be a 1946ist; the USSR was threatened with nukes if they did not honor their agreement to withdraw troops from Iran.
Or maybe I'm a 1953ist; the Korean War came to a halt after we threatened China with nukes.
Maybe I could even be a 1991ist; reportedly, Saddam Hussein was threatened (or we wanted him to think we were threatening him) with nukes if he used chemical weapons against our troops.
Notice the theme?
There was never a real third world war because of the threat of nukes. Now that the nuclear attacks on Hiroshima and Nagasaki our now six decades in the past, perhaps it is time to make examples of dictators like Assad, Ahmedinejad and Kim Jong Il?
