This nationalism that you are maybe by mistake promoting is a tool for people in power to give them more power and not unite together against them. Stabilization of a country you are talking about is unfortunately stability of the rich politicians to rule over poor people while they suffer and die. That is a stable system that we shouldn't defend. This system shouldn't be stable, it should crumble and people of all nations should unite in their fight against their politicians, not foolishly support their leaders just because they are from their own region.

Russian, Chinese and US government have more in common then any of their citizens do with their governments. Same goes for politicians inside a country, like Biden and Trump. They fight each other for more power, but they easily unite against people that threaten their power. Don't think for a second that if US citizens went against their government, Biden (or Trump) wouldn't ask for (and receive) support from Russian and Chinese government.

It is not US vs China or Russia, it is governments vs the people. Other narratives are just tools to divide people, nationalism was built for this purpose. For centuries regular people didn't feel like part of a certain nation, it was years of successful propaganda that got people thinking like they have more in common then just some same tyrant ruling over them.
