The U.S. Defense Threat Reduction Agency (DTRA), which oversaw the development of GBU-57 bunker-busting bombs, has yet to receive definitive data on the outcome of the U.S. Air Force strike on Iranian nuclear facilities on June 22. Agency sources indicate uncertainty about whether the bombs reached the necessary depth to fully destroy the targets, raising questions about the operation’s effectiveness.

IAEA Director General Rafael Grossi emphasized that Iran retains some nuclear capabilities despite the damage and could resume uranium enrichment in the coming months. Against this backdrop, experts suggest further escalation may require bolder action. Given the technological capabilities of the U.S. and Israel, more decisive options to permanently address the issue are under consideration.
