political incarnation

i was reading the news today to quench my political thirst, that i came to an article on Iran-US relations. the position that Iranians had taken had gone from firm and righteous stance to a lame and ridiculous one!
previously, during bush time, Iranian were saying that they will negotiate if only there's no preconditions. it has been one thing that i was in agreement with our current government. there should not be any preconditions for negotiations. it seems that new US office had reconsidered their stance and not only there would not be any preconditions now to negotiate with Iran, but also Obama sends a new year message to Iranians, not excluding the Government.
now what is our politicians response to that change of rhetoric? they now have preconditions for negotiations! i don't really care whether we have relations with US? Having relations will make life easier but if there are no relations then life is not impossible.
one thing that our politicians are missing, is that time for clever plays and get ride for free is over. just as bush could get to nowhere for free and seeing the world from a defiant eye, Iranians can't as well. now US has a world behind his policies. they are now really leaders with consent of others.
i'm afraid the bush's soul had been in to pieces and each piece had reincarnated in Iranian politicians body!
