I wasn't a Trump guy either, but then I see how the liberals think today. Threads like this. How dare the POTUS want the nation he is elected to lead do well. There is nothing wrong with this, I honestly am baffled that this is an issue to you.
That oversimplifies what Trump says and what he means, and obscures it.
His entire life has been focused on zero-sum gamesmanship. He and his Base view world politics as if it were an NFL game. That's why his supporters have jettisoned the idea of compromise when election results only offer a few points difference between winners and losers, and they lost the popular vote -- a fact that they keep trying to sweep under the carpet with outright lies.
The future of the human race hinges on whether we revert to a tribalist mentality, thus encouraging other countries to do the same -- or we engage in collective solutions for collective problems like climate change. Nationalism will pull us toward war, and war will further deplete the resources needed to save the world from itself. Add in all the racist memes with the racist component of the Base, and the difference between what is said and what is meant gets clearer. Trump and his Base see America as just a modern Roman Empire that must be promoted -- no less defended -- at all costs in "Zero-Sum Mode."
Maybe it deserves a Malthusian perspective to put it into focus. Trump and his Base only care if Americans have a better place at the table. They'd rather not face the problem and solution of providing a place for everyone at the table. And this is not the road to progress. It's only a repetition of conflict known all too well in human history.
