Last summer, the United States struck several nuclear weapons facilities in Iran.
In the wake of the strikes, carried out by the highly advanced American B-2 bombers, President Donald Trump declared that the Iranian regime's nuclear capabilities had been "obliterated."
However, questions arose in the wake of the strikes about what was actually destroyed.

In the intervening months, the U.S. has tried to negotiate with the Iranian regime to reach a nuclear deal and Trump has repeatedly threatened the regime.
Recently, the administration began to float a potential strike, while maintaining that the nuclear program had been "obliterated," leaving the justification for doing so unclear. In his address after Saturday's strikes, Trump mentioned "imminent threats from the Iranian regime," missile and nuclear capabilities as well as regime change.
Iran has stated numerous times that it doesn't want nuclear weapons but believes it has the right to use nuclear power for civilian purpose.
A recent Defense Intelligence Agency memo suggested Iran was looking to develop an intercontinental ballistic missile by 2035, but Trump suggested missiles could be capable of reaching the U.S. "soon."

Here's how the events have unfolded.
June 12, 2025:Israel launches a series of preemptive strikes against Iran, hitting military targets including the nuclear program. A dayslong conflict erupts.
June 22, 2025:U.S. launches Operation Midnight Hammer, with more than 100 planes, including seven B-2 stealth bombers, targeting three nuclear sites in Iran. In the wake of the strike, Defense Secretary Pete Hegseth said the country's nuclear ambitions were "obliterated."
Hegseth said at the time that the scope of the operation was "intentionally limited" to give the Iranians a chance to negotiate and the attack was not about "regime change." At the same time, Israel said that it struck "dozens of military sites" in Iran.
Trump floated the idea of regime change at the time writing on Truth Social - "It's not politically correct to use the term, "Regime Change," but if the current Iranian Regime is unable to MAKE IRAN GREAT AGAIN, why wouldn't there be a Regime change???"
