Elist has published this global graphic information on nuclear weaponry.
Yesterday I read reports that Iranian passenger planes had been refused refuelling at some European airports, as part of the tightening sanctions regime driven by the US, as part of their "strategy of containment" of Iran.
Iranian planes have a high accident rate as the state finds it difficult to buy new aircraft and aircraft parts due to sanctions. Suspicion that Iran might want to develop nuclear weapons is given as the reason for the sanctions.
Israel, which is known to have nuclear weapons, is not subject of any sanctions.
This is the current state of play. For decades, we were told that "mutually assured destruction" (MAD) was keeping us safe. The idea was that no one would start a nuclear war without knowing it would be the last thing they every did. Since Reagan, and "Star Wars", the US has resumed devising "nuclear defence" that would theoretically allow a first strike, with responding missiles being knocked out of the sky.
Hard to see how we'll ever be able to get rid of this dangerous junk.
