When the Nazis came to power in Germany, things became increasingly difficult for the Jews. It began with restrictions on daily activities, then vandalism, then beatings, then, well, we all know what 'then' was.
Anyway, up until the last possible moment, opinion was divided between the optimists, who believed that this was just a passing phase, and the pessimists, who were not so sure.
Eventually we learned which opinion was correct and, "The pessimists went to New York. The optimists went to Auschwitz." became part of the world's lexicon.
And now we have Iran and the Iranian nuclear...'agreement?' And again there is a difference of opinion about what the future will bring. Only this time, it's not just the opinion of the Jews that matters, 'Death to Israel.' This time we have company, 'Death to America.'
And if we go ahead with this, 'American diplomatic triumph', and unfreeze Iran's 150 billion dollars to use as they see fit, allow them to import ballistic missile technology in 8 years and purify uranium to the level necessary to build a bomb in 10 or 15 years, what then?
Will the moderates in Iran gradually change the nature of the regime as the optimists believe they will? Will it really be Atoms for Peace? Hummus not Hamas? Or will the question one day be,
"Where did everyone go when there no longer was a New York?"
