In an appearance on CNN's "State of the Union" program, Ambassador Richard Holbrooke noted Iran has had three decades of acrimonious tension with the United States.
"We're not going to eradicate 30 years of bitter disagreements in one meeting," Holbrooke said in the interview. "But I want to be clear here that the United States has been asked repeatedly since Jan. 20 how we feel about Iran participating in meetings on Afghanistan and Pakistan."
The meeting will take place between U.S. Secretary of State Hillary Clinton and a group of Iranian diplomats at a United Nations-sponsored meeting Tuesday in The Hague, Netherlands.
