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.
