President Donald Trump spoke about his reported plan to deploy the largest nonnuclear bomb in the U.S. military’s arsenal, known as the “mother of all bombs,” to force an end to the war in Iran.

The GBU-43/B Massive Ordnance Air Blast, or MOAB, bomb would be used in possible strikes against Iranian energy infrastructure and nuclear facilities. The administration is considering the plan as the conflict remains unresolved over seven months after its start.
