The 12-day conflict between Israel and Iran has raised doubts about the sustainability of the ceasefire and the future of nuclear negotiations. Following US-brokered peace, Iranian officials express skepticism about resuming talks with the US, citing military threats as a barrier. Iran has halted cooperation with the IAEA, and satellite images show ongoing activity at its nuclear sites. The conflict remains unresolved for Tehran, which reports significant civilian casualties. The strategic goals of Israel and Iran are at odds, complicating the potential for an agreement.
