The US economy will not decline for some time with the expansion it has had under Trump up to this date. Trump remains in office for another four years he will have time to rid the world of the Central Bank strangle hold on the worlds economy.
All nations need to realize their nation will be responsible for their own economy.
Trade deals with other nations is the global economy. They should equally benefit each nation according to their GDP output.

Thanks JAP. I agree with all you've said. We're both old enough to remember the economy of the 60's when there was real prosperity and a hope for tomorrow when the American dream was alive. Then they ginned up another war and it's been downhill since then ... until Pres Trump.
