Yep. Other countries would attack Saudi Arabia if they enriched Uranium past reactor-grade. As you said, other countries don't want Saudi Arabia having nukes.
Edit: Hell, even enriching just up to reactor-grade might be enough, as other countries would suspect they are going further. It's one of the reasons many countries with reactors buy their Uranium from others and submit to regular checks. They don't want any doubt about what the fuel is for.
"In February 2023, the IAEA reported having found uranium in Iran enriched to 84%...the Iranians have been openly enriching uranium to 60% purity, a breach of the 2015 nuclear deal." Source that also contains a shitload more details and sources out the ass.
You generally enrich to 3% - 5% for nuclear reactors, with some designs asking for up to 20%. Iran enriching Uranium to 60% and 84% isn't for reactors...
