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.
