In the US, only a mass abandonment of national identity could suffice to dissipate the current passions. “globalists” with no allegiance to anyone but themselves, such as we are seeing with major corporations and their mandarins, would ally with foreign hegemons of convenience, mostly Chinese, by present context.

I think you have it exactly backwards. We are currently, right now, "held in economic bondageby the global financial, cultural and governmental entities."
Without Washington DC imposing these conditions, they would not exist. We would be energy independent and food independent. What would the global elites be able to do to us other than starting a war against us?
