U.S. and Israeli strikes in 2025 and early 2026 inflicted extensive damage on Iran's enrichment facilities, centrifuge production, and nuclear weapons development sites, leaving the program largely inoperable and requiring substantial reconstruction before any weaponization timeline could resume. Recent satellite imagery from September and October 2026 shows renewed activity at the Minzadayi compound near Tehran, indicating Iranian efforts to clear debris and restore capabilities, yet analysts assess that surviving underground assets and limited surviving centrifuges remain insufficient for rapid progress toward a weapon by the end of 2026. Trader consensus at 96.4% for "No" reflects these structural setbacks, IAEA oversight gaps, and historical precedents for proliferation timelines. Late diplomatic breakthroughs, undetected covert advances, or unforeseen escalations remain the primary variables that could shift probabilities.
