After the strikes, how would the US secure Iran’s enriched uranium?

When War Secretary Pete Hegseth was asked recently whether U.S. forces would ever move to secure enriched uranium reportedly stored at Iran’s Isfahan nuclear complex, he declined to say, citing operational security.

The exchange highlighted a question the U.S. and Israel's air campaign alone cannot answer: even if U.S. strikes degrade Iran’s nuclear infrastructure, who would physically secure the enriched uranium, and how?

Iran is believed to possess a significant stockpile of uranium enriched to 60%, near weapons-grade.
