Efficiency starts to matter in a near-peer conflict.
I live in the US. A near-peer conflict involves a nuclear exchange. The world will change in ways forever that none of us can ever foresee at that point.
A near-peer conflict involves a nuclear exchange
Respectfully, I think you're misunderstanding the term. The term is meant to represent the level of resources and weapons each combatant is bringing to the theater of conflict.It does not mean that the two sides are necessarily using the most destructive possible weapons in their arsenals. A hypothetical US/China armed conflict over Taiwan (god forbid) would be "near-peer" even if neither side goes nuclear.
"Near-peer" is meant to distinguish that sort of conflict from, let's say, US vs. Taliban in Afghanistan where the two sides had vastly different levels of technology and capability.
Or maybe you're making the point that two nuclear states would be hard-pressed to fight an open war that did not devolve into a nuclear exchange. Which is a very valid concern. If that's your point, I apologize.
