Faltering US support for the Ukraine will tempt Russia into more territorial expansion towards or even into NATO.
China will probably ramp up aggression against Taiwan and against the Philippines. It is a minor miracle that no lethal shots have yet been fired in the persistent and aggressive military incursions into Philippines territorial waters. Several navy vessels have already been damaged this year.
I believe that the best way to release tensions in the Middle East would be by improving relations with Iran - but Trump bombed the deal that would have enabled that. The relqtive economic stength of the US could have been a good motivatir. Now Iran is aligning itself with Russia.
