Regional Security

The United States and Israel's joint military campaign against Iran is upending the strategic order of the Middle East in ways that extend far beyond Tehran. The strikes have killed Iran's Supreme Leader Ali Khamenei, targeted Iran's military and nuclear infrastructure, and triggered retaliatory Iranian attacks across the region. As the war enters its second week, a second and potentially more consequential shift is taking shape. With Iran's role as the dominant pole of regional opposition to Israel now in question, a new rivalry is hardening between Israel and Turkey, one that carries different stakes, different risks, and a far more unpredictable trajectory than the confrontation the current war was designed to resolve. Understanding this emerging fault line requires examining both the structural forces pushing the two states apart and the domestic political dynamics that risk turning competitive rhetoric into irreversible confrontation.

Amid the intensifying confrontation between Iran and Israel throughout 2025, the prospect of a direct strike against Israel’s Dimona nuclear facility has moved from a remote possibility to a plausible escalation scenario. As military operations increasingly target strategic infrastructure on both sides, the regional system faces the risk of a threshold breach—one that could trigger not only military and political consequences but also a multidimensional crisis involving radioactive contamination, mass displacement, and economic collapse across multiple states.   While Israel would undoubtedly bear the immediate brunt—facing mass civilian evacuations, irreversible environmental degradation in the Negev, and the paralysis of its agricultural and tourism sectors—the ripple effects would extend far beyond its borders.   Jordan’s border regions and agricultural zones in the Jordan Valley could face contamination and humanitarian strain, potentially requiring the evacuation of tens of thousands of people. Egypt’s Sinai Peninsula and northern Suez region could suffer fallout exposure, disrupting global shipping through the canal and threatening the Red Sea tourism corridor. Saudi Arabia’s northern provinces, including areas tied to its Vision 2030 megaprojects, could face both environmental and demographic disruption.
