Just a reality check: the United States is currently funding and providing military equipment to Israel, who is carrying out an ethnic cleansing in the Gaza strip. Apparently, democratic governments also have a problem following the rules.

With the far right on the rise, the rules will disappear, because their ideology is "might makes right". That is the mindset of a maffia boss. War and conflict will follow, those who are not powerful enough get trampled.
I also assume you don´t want to know what a non rule based international order will look like. Things are depressing, but can get worse than where we are now.
Society needs to get their act together, but also desperately needs a healthy debate. Corporate media effectively block that, they rather sell the Politeia as entertainment. Still, the onus is on the people.
