As global players dissasociate themselves from individual countries, it results in a bifurcated global economy made up of a global class that is able to leverage international labor markets, and national classes who are more reliant on the well being of their respective nation.
Globalization was based on a very profitable codependency: we send you whatever you need: resources, manufactured goods, people, either as a workforce or as sex slaves, and you the West pay for that.
And then the West send back expensive goods -processed food, cars, etc.- and waste products, until recently.
This simbiotic relationship was possible because of cheap fossie fuels, cheap energy, cheap labor and huge logistic chains, cheap money to delocalize and a lot of corruption. If those elements that were cheap become expensive, the relationship starts to get murky or stips.
The decline of nations will be replaced by a purely economic world order dominated by multinational corporations and, to a lesser degree, those who have leveraged technology to access the fruits of globalization.
In this new world, the global class will hardly blink when nations fail, while the national classes, who are more closely tied to their local and national economies, will face greater uncertainty.
