You are right. We could just Not.
NK could just...stop sending raiding parties to SK and focus on resilience. After a decade of no border incidents, SK would probably get sick of the US and kick them out. The US could also stop fucking about in the ME, if only we had solar panels instead of oil derricks. We'll have slar panels soon enough.
But we both know that the above is just dumbass wishful thinking, because the ruling class of every country is psychopathic. Kim doesn't give a fuck, Xi gives few fucks, trump gives no fucks, Putin gives no fucks, that's what leadership and hierarchy is. Identifying the person who truly has the fewest fucks to give when it comes to others.
