>>508267706 (OP)Donald is doing this for "America First".
Because we are the foundation of today's America.
We control the dollar, we implement monetary policy, and we ensure employment stability.
We also formulate racial adjustments and management.
We create various art in pop culture such as movies and TV to promote American freedom and equality to the world.
What you call "American culture" is actually "the culture of us who immigrated to America".
If we disappeared America would just be an irrelevant third world shithole.
