The 2026 US strikes on Iran followed a convergence of factors: Iran's nuclear enrichment reaching 90% weapons-grade, Houthi and militia attacks on US bases, Hormuz shipping threats, and collapsed JCPOA negotiations. The immediate trigger was Iran's test of a nuclear device.
The US launched strikes after Iran enriched uranium to 90% weapons-grade and reportedly tested a nuclear device, combined with escalating attacks on US forces by Iranian proxies and threats to close the Strait of Hormuz.
The situation involved escalation on both sides. Iran accelerated its nuclear program and proxy attacks, while the US increased sanctions and military presence in the region.
