It all depends how one views our country. Obama and the liberals believe we should function as the sources of financing for the world's "collective" Trump and his supporters believe we should operate on the concept of America first. Our unbalanced trade deals have create massive trade deficits. We end up financing these world organization rainbow chasing programs and use are military to support NATO countries who are not living up to their financial commitments. Those are just a few things Trump is working on correcting this issues. 
Now I understand dropping out of the Paris accord was like a knife in the heart to you, but in my opinion there is no reason we should be giving any European bureaucracy billions of dollars. Trump is doing his best to drain the swamp, Obama and his ilk are the swamp and now we are finding some in our own party are also members.
