The United States and Israel launched coordinated strikes on Iran early Saturday after negotiations over Tehran’s nuclear program collapsed. For weeks, talks had strained under U.S. demands to dismantle key nuclear infrastructure and halt long-range missile development.

Iran rejected the terms as violations of its sovereignty. As diplomacy faltered, military planning intensified in Washington and Tel Aviv. When the strikes began, they marked a decisive shift from negotiation to open confrontation.

Explosions were reported in several Iranian cities, and air defense systems activated. The move signaled that both governments believed deterrence now required force rather than further dialogue.

In an online video, President Donald Trump called the action a “massive and ongoing operation,” framing it as calculated and necessary. BBC News and Associated Press reported strikes on sites tied to military infrastructure, with smoke rising over Tehran.

Some reports suggested areas near offices linked to Supreme Leader Ali Khamenei were affected, though details remained unclear. Iranian state media downplayed the damage as emergency crews mobilized.

Israel confirmed its role, describing the attack as preemptive. Prime Minister Benjamin Netanyahu supported the joint operation, calling Iran’s capabilities an existential threat. Air raid sirens sounded in Israeli cities amid reports of retaliatory missile launches.

Global markets reacted nervously, with energy prices rising on fears of regional disruption. Lawmakers in Washington debated executive authority, while governments worldwide urged restraint to prevent broader war.

As tensions escalate, uncertainty dominates. Supporters argue the strikes restore deterrence; critics warn of retaliation and prolonged instability. Whether this confrontation leads back to diplomacy or deeper conflict remains the defining question.
