VP Debate Quote: Biden Asks Ryan, 'You're Going to Go to War With Iran, Is That What You Want to Do Now?'

Vice President Joe Biden defended the administration's handling of the Iranian nuclear threat in tonight's vice presidential debate, arguing that the Iranian economy is being crippled by harsh economic sanctions.

"These are the most crippling sanctions in the history of sanctions, period. When Governor Romney

is asked about it, he says we have to keep these sanctions," Biden said, asking Ryan if he wants to go to war with Iran.

Ryan responded that Mitt Romney's plan is to prevent war with Iran. Biden asked how they would prevent war if they say there is nothing more that the U.S. could do regarding sanctions and diplomacy.
