Iran’s U.N. Ambassador Mohammad Khazaee didn’t attend the latest U.N. Security Council meeting on Iraq. But the moment the 3-hour session was over the Iranian delegation was circulating a strongly worded letter from Khazaee that had a very clear message for the administration of U.S. President Barack Obama: Stop talking like Bush.

He was responding to less than two dozen words on Iran in U.S. Ambassador Susan Rice’s speech to the council during a routine review of U.N. activities in Iraq. Rice said that U.S. policy "will seek an end to Iran's ambition to acquire an illicit nuclear capacity and its support for terrorism.”

Those words clearly infuriated the Iranians, who have been toning down their anti-U.S. rhetoric since Obama took over from George W. Bush five weeks ago.

"It is unfortunate that, yet again, we are hearing the same tired, unwarranted and groundless allegations that used to be unjustifiably and futilely repeated by the previous administration," Khazaee said in a letter to the council's current president, Japanese Ambassador Yukio Takasu.

"Instead of raising allegations against others, the United States had better take concrete and meaningful steps in correcting its past wrong policies and practices vis-a-vis other nations, including the Islamic Republic of Iran."
