Well a lot of that starts with not flying them across your own country fully armed. Nukes are incredible hard to set off, you could blow one up with a missile.

Well a lot of that starts with not flying them across your own country fully armed. Nukes are incredible hard to set off, you could blow one up with a missile. It would be a mess but that is not enough to set off the full on detonation of the core material. The scary thing isn't a nuke going off accidentally, I mean if you keep enough of them it's just a certainty on a timeline. The scary thing is a miscommunication about whose it was, and the vengeful actions that follow.
