United Nations Human Rights official Richard Falk has picked out America’s relationship with Israel as one of the factors that create "blowbacks" such as the Boston bombing.

In his foreign policy journal article titled, ‘A Commentary on the Marathon Murders’, Mr Falk wrote: “As long as Tel Aviv has the compliant ear of the American political establishment, those who wish for peace and justice in the world should not rest easy.”

Mr Falk included America’s foreign policy since the 9/11 attacks as well as “a series of disappointing reactions by Obama” as explanations for the recent Boston violence in which three people were killed. Mr Falk criticised Barack Obama’s approach to the Middle East and “the strong pushback by Israel and its belligerent leader, Bibi Netanyahu.”

Mr Falk, who is the UN Human Rights Council’s permanent investigator into Israel’s violations of international law, predicted further violence in the future. He wrote: “The United States has been fortunate not to experience worse blowbacks, and these may yet happen, especially if there is no disposition to rethink US relations to others in the world, starting with the Middle East.”
