This election should not be Obama Vs Romney, It should be "Obama And Romney" Vs "The Other Candidates". There is no real difference between Obama and Romney. The real change for US are in the "Other Candidates".
This is a great description of the world but a western world. It is not Iran the problem, is U.S. the problem. The only country in thw world that has used WMD against other nation has any moral value to demant that Iran stop his nuclear program.
