The results happen and in deep red states immediately there will be increased calls to remove as much federal influence as possible from the state to increase autonomy, essentially slow walking a separation.

Given the amount of lawfare used against Trump and his allies, we'll see a similar situation as what's happening New York or China where those with money assume it's not safe thanks to government interference so move it to areas they feel is safer, crippling a lot of East coast and California as well, you might end up with increased shipping to through Texas and Florida as a result.

With the inability to utilise the military effectively under Biden continuing under Kamala, China would make it's move to take Taiwan, disrupting global logistics regardless of result, I can also see Venezuela finally having it's war with Guyana seeing the weak American leadership which could affect trade there but the biggest one is there is growing tension between Egypt and I believe its Sudan over water rights which would cripple all trade going through the Nile more than Yemen has.

America having weak military leadership and an incompetent foreign policy makers will hurt the entire world so expect a recession worse than 2007.
