Iran's biggest Gulf Arab neighbors are considering joining the US-Israeli war against Iran, and could be pushed to if Tehran attacks their critical infrastructure, according to several people with knowledge of the situation.

Ray Takeyh, Senior Fellow for Middle East Studies at the Council on Foreign Relations, joins Bloomberg Businessweek Daily to discuss. He speaks with Carol Massar and Tim Stenovec.
