Nuke deal would 'roll back' Iran military: US adviser

A nuclear deal with Iran will significantly roll back Tehran's military capability, US Vice-President Joe Biden's national security adviser told a conference in Qatar yesterday.

Dr Colin H Kahl, speaking at the US-Islamic World Forum in Doha, said the current deal being hammered out was the best on offer, despite many sceptical voices in the US and elsewhere, including Gulf Arab states.

"Under the deal we are negotiating... Iran's military capability will be substantially rolled back," said Kahl.

"The deal we are negotiating makes us and the region safer."

The ongoing talks to finalise a nuclear accord between Iran and world powers, including the United States, are deadlocked weeks ahead of a deadline.
