The discussion about Iran's nuclear program seems stucked. It seems improbable that Russia will put much pressure on Iran, the US isn't really in a hurry to get yet another battle field and Ahmadinejad seems shortly after the contested elections not in a position to make major concessions. The only country really upset about all this is Israel - that remembers some radical pronunciations by Ahmadinejad.
That makes me conclude that the most elegant temporarily solution would be if Ahmadinejad took some of his radical statements about Israel back. Can please someone convince him that radioactivity is dangerous stuff and that the world expects from leaders who play with it signs of maturity and responsibility?
