When it comes to the nuclear talks between Iran and the West, no country watches as closely as Israel. Conflict Zone talks to Israel's former defense minister, Moshe Yaalon, who says the nuclear agreement was a mistake and a missed opportunity.

Western nations are rushing to revive the 2015 Iran nuclear deal amid reports that Tehran is boosting its uranium enrichment.

European diplomats have called a pause in talks on Iran's nuclear program "disappointing." EU envoy Enrique Mora has said only weeks remain to save the deal, as Iran ramps up uranium enrichment.

With Tehran feared to be weeks away from a point of no return on nuclear weapons, are we looking down the barrel of an arms race in the Middle East? With little optimism in the air for the current round of talks in Vienna, where might this leave the Biden administration? Does the US have the stomach for a fight? And is a fight really what's unfolding? Traditional lines in the sand seem to be out the window as the same Gulf states that are cementing new ties with Israel are also keeping channels open with Tehran.
