"My guess is that some type of negotiations is going on with Iran."
My guess too.
"the implementation of the sanctions to be discussed at the Security Council next week they have allowed Khatami to visit.."
Sanctions would be important even politically, but they aren't and won't be. What sanctions btw?
"We should not forget that the economic situation in Iran resembles the situation in the former Soviet Union prior to Gorbachev."
It does, doesn't it? Not as meaningful and Soviet Union isn't comparable to Iran and Gorbachev isn't Khatami.
But hope you are right.
I will reveal a secret: I have, since 1979, guessed that "the Iranian theocrazy will fall next year". One of the coming years I will be right. ;-)
