I don’t think I’m convinced physical interactions are defense dominant. The easiest-to-formally-certify defense is to enclose something in a hunk of impenetrable matter, and that only can be certified up to a given impact energy level. Above that energy level, the defense will simply be stripped away. Only MAD seems able to be game theoretically durable, and certifying that a MAD situation will endure requires proving through a simulation of the opposition.
