Israel’s conflict with Iran represents far more than another Middle Eastern crisis – it marks the emergence of a dangerous new chapter in nuclear rivalries that has the potential to reshape global proliferation risks for decades to come.
What began with Israeli strikes on Iranian nuclear facilities and other targets on June 13, 2025 has now spiraled into the world’s first full-scale example of what I as an expert in nuclear security call a “threshold war” – a new and terrifying form of conflict where a nuclear weapons power seeks to use force to prevent an enemy on the verge of nuclearization from making that jump. As missiles continue to rain down on both Tehran and Tel Aviv – with hundreds dead in Iran and at least 24 killed in Israel – the international community is witnessing the collapse of traditional deterrence frameworks in real time.
