Obama’s ‘Diplomacy’ Wins a Republican Endorsement

By Adam Graham-Silverman, CQ Staff

The ranking Republican on the Senate Foreign Relations Committee parted ways with his party’s presidential nominee Wednesday by endorsing Democrat Barack Obama ’s approach to diplomacy.

In a lengthy speech at the National Defense University, Indiana Sen. Richard G. Lugar weighed the benefits of talking to foreign leaders, including U.S. enemies, against other actions, such as military force. The issue marks one of the sharpest divides between Obama and John McCain , who has called the Democratic nominee naive for suggesting that he would sit down with leaders such as Iranian President Mahmoud Ahmadinejad.

Lugar, however, praised Obama, noting that isolation often does not resolve contentious issues.
