  1.  kaiss-K -Ci  under Trump's watch Iran proved they could have made a weapon by enrichment of 1600 pounds of uranium to 20% , so they could have done a smaller amount to 90% required for a weapon no problem. So they have 300 pounds or about 150 kg of U 235 enough to make 75 nuclear weapons. A nuclear weapon only needs about 2kg of enriched uranium to about 90%. Just remember enrichment is logarithmic as in to 20% is over half way there to weapons grade.
