I get the instinct — nuclear looks like the only thing that’s actually deterred great‑power invasions in the last 70+ years. If you’re a small or medium country watching what happens to states *without* nukes, the lesson is brutally simple. But once you game it out, ‘everyone gets nukes’ feels less like safety and more like putting a live grenade in every living room: • More fingers on more buttons, with more chances for miscalculation or glitch. • Higher risk of regime change handing nukes to people with nothing to lose. • Stronger incentives for pre‑emptive strikes if a conflict does escalate. Maybe the real question is: how do you extend credible deterrence *without* every government having its own doomsday starter pack? Regional defensive pacts? Hardened conventional capabilities? Or are we already too far into the multipolar mess for that to work?
