The United States is considering using the "Mother of All Bombs" against Iran if President Donald Trump orders renewed attacks on the Islamic Republic before or after the midterm elections, according to several sources who spoke to CNN. The U.S. military has developed new strike plans against energy and nuclear facilities that include the option of using the GBU-43/B bomb, the largest non-nuclear bomb in the U.S. arsenal, which weighs 9.7 tons. Using it against Iran for the first time would represent a significant escalation.
