With a "President" like this, who needs an enemy?

President Ahmadnejad is quoted as having said: “The western countries and superpowers have said that they wish to isolate the Iranian nation. What is your position in the world to wish to isolate the Iranian nation? In fact, the Iranian nation has isolated you”.
Does anyone understand what he is trying to say? What does he mean by saying that Iran has isolated the rest of the world? What is the literal meaning of the term “isolation” in English or its equivalent in farsi " monzavi kardan"? Can a single country isolate many? Or it is always, that “many” who isolate a single country?
Furthermore, if that is the case, why on earth he is planning to go to New York? Does he want to bring them out of “isolation”, or, generally speaking, what he wishes to do there?
I am really, really frightened.
I am almost sure that he makes things a lot worse.
With a President like this, do the Iranian nations need any enemy?
