But who else than the americans should get America back? The Germans? The Japanese? They never owned americano so I think it will be difficult to give it BACK to them?
By the way: If you believe in state (I do not) the only owner of one state can be the citizens of that state.
But you need a state that coorporates with other countries. If he builds a wall to Mexico you can create a good economy and if you want to give everyone work and lower the taxes you should have a huge economy. For me the economy is the key. But for him it is racism.
