Negotiations resume Monday in Vienna, Austria over Iran's nuclear program.
Representatives from the U.S., France, Russia, and the U.N. nuclear agency will meet with Iranian officials to nail down details of a proposal that could see Iran send its enriched uranium to Russia.
Exporting most of its enriched uranium could keep Iran from having enough material to make a nuclear bomb.
Later this month, the Islamic republic will allow U.N. Inspectors from the International Atomic Energy Agency to examine their uranium enrichment facility under construction near the city of Qom. It is the same nuclear plant that President Obama,French President Nicolas Sarkozy and British Prime Minister Gordon Brown announced to the world, just days after being notified by Iran of the facility.
Some believe that Iran's new willingness to negotiate may come from pressure being applied by the Russians.
"This time, it seems to me they are moving a bit to suggest to Tehran that Russia should not be taken for granted or ignored when it comes to meeting what Russia also says are legitimate expectations about Iranian behavior," said James Collins, a former U.S. ambassador to Russia.
But, he said, the "administration probably overplayed their hand" in that the Russians' patience for negotiating with the Iranians could stretch far beyond that of Washington.
