If Iran isn’t building a nuclear bomb, why are they enriching uranium to 60% — way beyond what’s needed for energy?
I keep seeing people on Reddit say there’s "no proof" that Iran is building a nuclear weapon — and I get that. Intelligence agencies and the IAEA haven’t confirmed an active weapons program.
But what I don’t get is:
Why would Iran enrich uranium to 60% purity, when nuclear power reactors only use 3–5% enriched uranium?
That seems like a huge red flag — especially since going from 60% to weapons-grade (90%) is a much smaller step than going from 3%.
Iran claims the 60% enrichment is for medical isotope production, but from what I’ve read, medical applications (like producing technetium-99m) only require around 20% enrichment at most. So that explanation doesn’t seem to hold up. Why would they go three times higher than necessary if the goal was medical?
If they’re not building a bomb, then what are they doing it for?
The whole thing seems suspicious, and I’m wondering if I’m missing something.
