there are many reasons to do nuclear research beyond medicine, for batteries like the ones powering the voyager space craft, nuclear reactors come in a wide variety of configurations, and many of them actualy produce more radioactive elements that then need to be managed. 60% is nothing,80% is nothing, it needs to be 93%++, and LOTS of it to build a bomb, and given the number of bombs already arrayed around Iran, they would need 100's and all the infrastructure to become a credible threat , for which they plainly dont have the money to afford. The wildly unpopular leaders going after Iran need a scapegoat, or rather a continious supply of scapegoats, but have failed to recognise that the world is moving past them.
60% is actually very close to 93%. To go from natural uranium (<1% U235) to 60% represents the vast majority of the effort. From 60% to 93% is actually quite quick; most of the material is already U235. And they already have enough to build maybe a dozen bombs.
They also have (had?) a very active ballistic missile program, and have conducted implosion experiments.
The constellation of evidence is quite clear: Iran is a threshold nuclear state with all the pieces necessary to credibly threaten the region (and soon the US homeland) with nuclear weapons.
Talking hypotheticals, while the actual threat to the region are the usa and israel
Nice segue.
We've gone from, "The amazing Islamic Republic of Iran isn't even capable of building deliverable nuclear weapons and they have lots of peaceful reasons to do enrichment to 60%!" to "Yeah OK, they are capable and they are indeed enriching Uranium for their weapons program--hey, look over here! USA and Israel!!!"
It's not a segue, USA and israel have been literally destabilizing the region for many decades now. They survive on chaos
