Valid points you make. However Trump is essentially saying nothing with this statement. Plus I'm of the mindset that if the U.S. had a very strong military securing its own country, kept the money for its own people and didn't devalue the dollar by printing and giving it away, it would have less need to rely on the foreign money gifting game. Imagine less need for buying allies because you are solely focused on the well being of your own citizens. Creates less foreign enemies as well.

Plus, owe you money with no concrete terms as previously stated is as good as gone.
