Trump rules out using a nuclear bomb on Iran: Why that matters

United States President Donald Trump has for the first time explicitly ruled out the use of a nuclear weapon against Iran, but has not denied US media reports that his administration is considering deploying the US’s most lethal non-nuclear munition , nicknamed the “mother of all bombs” in the near future. In an interview published on Thursday by right-wing American news site Newsmax, Trump suggested he does not plan to use nuclear weapons, but also clarified that the devastating aerial weapon, the GBU-43/B Massive Ordnance Air Blast Bomb (MOAB – ‘mother of all bombs ) “is not nuclear”. “I wouldn’t use nuclear. We don’t have to. We’re the greatest nuclear power in the world,” he told Newsmax.
