It's true, number one reason there hasn't been a way between powers since ww2. The 80s/70s both the Soviets and Americans constantly has their fingers hovering over the red button
There's new technology involved now though.Yes.
They have instead resorted to proxy wars which as you see, is what major nations have been doing since 1945.
USSR and US would back differing sides in conflicts and now you see Iran and US/KSA doing the same.
Proxy conventional warfare is the way forward.
Nuclear weapons has basically become a deterrent from having a home front in a conflict.
There's new technology involved now though.
Theoretically the US could nuke China and block every single nuke that comes at them, thus destroying the concept of mutual destruction
Apparently the new battlefield will be underground or in tunnels due to air support/nukes making infantry completely useless. Killing indooyars dog-eaters underground, away from prying eyes and the geneva convention?
