I was NOT expecting Number 4 Full list in comments

Experts are careful to stress that none of this analysis implies inevitability. Deterrence remains strong, and multiple layers of safeguards exist to prevent catastrophic escalation. Communication channels, early-warning systems, and diplomatic backstops are all designed to reduce the risk of miscalculation. However, the fact that such discussions feel increasingly relevant reflects a broader anxiety about the fragility of peace.

Much of that anxiety centers not on weapons themselves, but on human factors. Misread intentions, technological glitches, alliance pressures, and political ego all introduce uncertainty into systems that demand precision. History shows that wars often begin not because leaders desire them, but because control slips at critical moments.
