The Power of Moral Complexity

(1) Comments | Posted September 17, 2014 | 12:12 PM

Today, the citizens of the United States face some very difficult moral choices.

(10) Comments | Posted April 15, 2013 | 5:17 PM

Whether it is the CIA gaming Iranian revolutionary leaders by posing as a Hollywood film crew to rescue U.S. diplomats in 1980, the U.S. government, military and CIA...

The Decade for Peace in Israel-Palestine

(20) Comments | Posted May 14, 2012 | 11:05 AM

Having just returned from a visit to Israel where I spoke at a meeting of government scholars which included several negotiators who had been directly involved in past peace processes, one thing is clear: peace with the Palestinians seems impossible.
