Doomsday Machine

A Doomsday Machine is a theoretical, highly destructive weapon designed to cause catastrophic destruction if activated, often as a deterrent against attack. It operates on the principle that its existence alone discourages enemies from initiating conflict, because they risk total annihilation. In some contexts, it refers to a strategic military system that, once triggered, could trigger widespread destruction or nuclear retaliation, effectively preventing war by making the cost of conflict unimaginably high. The idea emphasizes the importance of preventing such devices from ever being activated due to their destructive potential.
