the goal is to never have to reach that

there's that cycle of armament and disarmament of which we've mostly seen one high and one starting low and another low now

this is to say and I hope it makes sense

it's to supposedly be good at something you hope you'll never have to do because it's a damn good way of signing your own death certificate

tldr: be good destroying your enemy in theory and hope it works out

that's MAD explained in a really bad way
