Most countries have deep economic ties to most wealthy countries, we’re in a global economy. Even subsistence farmers in subsaharan Africa buy more of their seeds than you can imagine from Chinese companies that do the bulk of their R&D in the US and western Europe, if US policy becomes extremely isolationist that will affect them.
Also, the US is one of the biggest climate emitors, if that ramps up instead of decreasing the whole world will feel that too.
Best of luck!
