It was never about nuclear weapons, Netanyahu has been saying Iran was one week away for over 30 years. Europe goes along as an excuse to support politically unpopular war to maintain US support for Ukraine.

the nuclear weapons program has cost about 2T USD for Iran, and definitely makes certain arguments for intervention more acceptable, but it doesn't negate the other side of the equation. the cost of intervention is still enormous. (and since the enriched uranium is an obvious target it is obviously even more protected)

its always oil and 'freedom'
