The Biden administration has worked hard for the US to return to the 2015 Iran nuclear deal, which former President Trump walked away from in 2018. On GZERO World, Ian Bremmer speaks to Ali Vaez, Iran project director at the International Crisis Group, who says the odds of renewing the deal in the short term are about 50/50. Now, reaching an agreement is more urgent than ever because Iran is closer to getting the bomb, Vaez explains, because the breakout time to enrich enough uranium for a single nuclear weapon is reportedly within weeks.
