Former United Nations Ambassador John R. Bolton says his major concerns include “the nuclear proliferation issue, as manifested both in Iran and North Korea ... relations with Russia, and the approach to the U.S. intelligence budget,” which is facing a $25 billion cut over the next 10 years. Mr. Bolton is critical of the White House for claiming that the killing of al Qaeda leader Osama bin Laden last year has diminished his terrorist network. (Associated Press)
