You have an interesting version and concept of history and current events. Even if the Dems win the house, and even if they win the next Presidential election, nothing will change about the US because there is nothing any President can do to save it. The problems America has are systemic and ingrained in the economy. Trump is just the poster boy, bringing them out to the attention of the world. America has gone from America 80% world GDP to less than 20% world GDP in two decades. That will never be undone by ANY future President.

South Korea is actually taking over the role of America as the world's arms manufacturer, (heading for fourth place) and that will not change no matter what happens in the US politically. As the world shies away from American arms, South Korea is determined to pick up the slack. Once they get market share, they will not lose it. They have the industrial capacity to beat out anyone, even the US.
