United States military planners are reviewing high-level contingency strategies, including the possible deployment of massive conventional ordnance against heavily fortified underground sites in Iran. The discussions center around the GBU-43/B Massive Ordnance Air Blast (commonly known as the “Mother of All Bombs”) and specialized deep-penetrating bunker busters. The deliberations highlight mounting anxiety among Western intelligence agencies regarding the accelerated hardening and expansion of Iran’s subterranean nuclear enrichment facilities.

Regional partners have expressed concern that any kinetic strike on Iranian nuclear infrastructure could trigger widespread retaliation across the Middle East.
