You joke about nukes, but since they're such an "unthinkable" weapon they've become almost useless for most people who have them. You need them so that others with fewer compunctions are not able to steamroll you, but as an actual help to the kinds of conflicts currently going on and likely to happen in the future, they're just not as effective.

Whether that's fast cruise missiles, more powerful drones, more disposable drones, robot warriors, cyber-warfare, etc. militaries are trying to find the technology that breaks the stalemate caused by MADD.

Nukes simply existing may have saved more lives at this point. That could, of course, change in seconds at any time.
