The USA currently has a problem where a large portion of the US population no longer trusts the USA. That population shifts depending on whichever group is in charge of the federal government
Maybe this is not the way to repair that trust, I don't know. But I think for a lot of people, "Stop sending tons of our tax money to other countries" is a step to repair some of that trust with the population
The next step would have to be "start re-investing that money back into America" but we'll see if that actually happens
