Ahmedinejad is 'At It' Again

Iran's bellicose leader - Mahmoud Ahmedinejad - is at it again.  While at the United Nations, he repeatedly used provacative language to take stabs at both Israel and the United States, threating a war that "would know no boundaries."  It is hard to believe that even he could take himself seriously, but it is far from likely that he is anything but sane.  So what drives his repeated rants?  Could he be fearing an upcoming Israeli attack?  Could he be attempting to stifle the domestic opposition by reiterating the supposed external threat?  Or is he simply trying to provoke others agains US rule?

For an interesting look at his political acumen (not to mention his 'odd' theories), watch the video below where he deftly ignores every question from George Stephanopoulos.
