Bush made the remarks in an interview with National Public Radio today.
Washington charges that Iran is helping insurgents who target U.S. troops, a claim denied by Tehran.
Also today, Bush's chief spokesman, Tony Snow, said Iraq is free to seek closer ties with Iran, after Iran's ambassador to Iraq, Hassan Kazemi-Qomi, said Tehran wants to boost its military and economic role in Iraq.

WHAT IS GOING ON? On March 8, RFE/RL's Washington office hosted a roundtable discussion on relations between Iraq and Iran. Although most analysts agree that Iran has been actively involved in Iraq since the U.S.-led military operation to oust former Iraqi President Saddam Hussein, they continue to debate the nature, extent, and intent of that involvement.
The RFE/RL briefing featured WAYNE WHITE, former deputy director of the U.S. State Department Bureau of Intelligence and Research's Office of Analysis for the Near East and South Asia, and A. WILLIAM SAMII, RFE/RL's regional analyst for Iran and editor of the "RFE/RL Iran Report."
