As Donald Trump celebrated “extremely good” progress in secretive Iran talks and twice extended his deadline to devastate the country’s power grid, Tehran quietly pulled a nuclear alarm of its own. Iran has signaled it could walk away from the Nuclear Non-Proliferation Treaty amid escalating strikes on its key facilities. Tehran is openly questioning the value of remaining bound by international limits. Lawmakers are now debating a move that could reshape the nuclear balance in the region, even as Iran claims it has no intention of building a bomb. With nuclear sites under fire and diplomacy in dispute, the next steps from Tehran could redefine the trajectory of this conflict.
