The United Nation's Palestine Monitor and Princeton Professor Emeritus Richard Falk blames the Boston attacks on the United States...

Why am I not surprised?  

Richard Falk also blames Israel for the Boston attacks too (weird, I did not realize Israel was occupying Chechnya).  Falk even goes farther than Dzhokhar Tsarnaev.  

This is not Falk's first controversial position.  How to you think he got the UN post as a United Nations Special Rapporteur on the situation of human rights in the Palestinian territories the first place?  As Alan Dershowitz notes, Falk supports positions that are antisemitic. And Falk is Jewish (well his family is Jewish, think Noam Chomsky)

Update:

Outraged by Richard Falk's highly offensive Boston comments. Someone who spews such vitriol has no place at the UN. Past time for him to go.

I am glad Susan Rice gets that Richard Falk's comments are beyond the pale, but she is naive if she thinks his views are not actually fairly common at the United Nations.
