I suspect this question assumes that all “superpowers” are the same, namely that they’re all capitalist imperialist states.
A recent video by Veritasium tries to answer this exact question : https://youtu.be/mScpHTIi-kM?si=ubCMDqPrrlqYBQI8
Superpower wars are expensive and extremely unrewarding. Neither wants them. Sometimes they may talk the talk but when it comes to dedicating the next 10 or 20 years to a constant resource drain with no chance of recovering any of that, they’ll find any excuse to get out of it.
What two superpowers?
Why of course the US and Bhutan.
As a USA citizen I spit out my drink when I read this. Had no idea what Bhutan even was. It’s now on my list of places to visit.
They don’t have visitor visas
Bhutan might have to move over. Yemen’s getting the upper hand over the US the past few weeks. :)
Unfortunately it may be impossible because of game theory. In a perfect world everyone would get along and no one would have to dump billions into the military. That’s impossible because there’s always a “rat” that uses this opportunity to invade and conquer defenseless territories. A rat kind of like Russia or soon potentially China.
Because of them now everybody has to invest in their military and we are all worse off because of it, this can also apply to nukes. One power will exploit their nuclear advantage over one who doesn’t, which is why the USSR and CCP, DPRK, and Pakistan developed nukes, their rivals had one too.
I encourage you to watch veritasium’s video on the concept of game theory and how it affects most things in our lives.
Only by ceasing to exist.
