Iran on Monday urged the United States to effect a "180 degree" change in its policies after the Democrats' victory over the Republicans in last week's midterm elections.
"If there is a 180 degree change in US policy it would be a good thing," Iranian government spokesman Gholam Hossein Elham told reporters.
"I hope that it is true that the United States will revise their policies and leave the region in peace, that they renounce their belligerent policies and stop supporting terrorist groups," he said.
"This would be a good thing. If the United States does this, the problems would be solved," he added, without elaborating.
