US and Israel Launch Strikes on Iran as Nuclear Crisis Escalates

Executive Summary

The United States and Israel have launched direct military strikes against Iran, and Iran has responded with counterstrikes, marking the onset of open interstate war in the Middle East. This escalation follows the apparent collapse of US-Iran nuclear negotiations, in which Washington demanded full denuclearization — terms Tehran was never likely to accept. The conflict represents the most consequential military confrontation in the region since the 2003 Iraq invasion. In the near term, the strikes reshape the security architecture of the entire Middle East and test every alliance structure from the Gulf to Europe. Energy markets, maritime chokepoints, and proxy networks across Lebanon, Iraq, Yemen, and Syria face immediate destabilization. The human cost to ordinary Iranians — already enduring decades of sanctions — now compounds with direct warfare against state infrastructure. On a five-to-ten-year horizon, this conflict will define whether nuclear nonproliferation survives as a governing norm or collapses entirely. If military force becomes the accepted mechanism for denuclearization, other threshold states will accelerate covert programs rather than negotiate. The precedent set here reverberates through every future conversation about North Korea, Saudi Arabia, and beyond. At the epochal scale, February 2026 may mark a turning point in humanity's relationship with existential risk. Interstate war between nuclear-capable and nuclear-aspirant states, waged under a doctrine of preemption, raises the probability of catastrophic miscalculation. The Anthropocene already tests civilization through climate disruption; adding great-power military conflict over weapons of mass destruction compresses the margin for error in an era when humanity can least afford it.
