How far could the nuclear storm go if a nuclear bomb hits Iran's gravel mountain? University of Chicago professor Robert Papp said Trump could face pressure to consider a nuclear strike on Iran's deeply buried Mount Makush facility, warning that the resulting "radiation boom" could spread far beyond the target. A model-based forecast shows fallout could spread across the Gulf, Afghanistan and Pakistan, with lower concentrations likely to reach parts of India depending on winds and output. Hypothetical scenario only.
