President Donald Trump faces the most daunting question of the Iran war: Will he put U.S. troops on the ground to secure the enriched uranium Tehran could use for nuclear weapons? Trump has offered shifting justifications for launching the war but has been consistent in articulating a primary objective in joining Israel in it is ensuring Iran will "never have a nuclear weapon." However, the Republican president has been more circumspect about whether he's willing to send troops into Iran to seize or dilute its enriched uranium. Iran's foreign minister told CBS that Iran offered to dilute the enriched uranium stockpile during talks with Trump's negotiators before the war began.
