Imo true internationalism is done through good diplomacy between contries, and mutual help towards the good of all.
The US suffers two huge problems, and I only talked about one in the context of tariffs because I lacked (and lack now) the time to go into the other. But in short, it has:
- the liberal/capitalist problem - an oligarchy without a nation, "citizens of teh world" who expect to be able to move their assets intantly (all that liquidity provided by financial markets, how they love both these things so much) to another country. And thereforw will seer to exploit each and every place they can get their beaks into, iunto collapse. I'm going with the giagnt vampire quid image. Including the countries they originated in.
- the imperial bureaucracy problem, which could easily be seen in the terminal days of the British empire, but can be seen in pretty much every empire even before their end. A whole class of people whose careers and socila position depend on there being imperial insteretss to manage, on behalf of the state. These, unlike the first, care about having a strong state. But the kind of state they need is a huge drag on the national economy, and all the empire can provide is financing by, indirectly, forcing those foreign populations under empire p«mannagement to pay tribute.
The way these two combined produced what the US is now. Sorry, I will try to write something clearer about these things later. But what I wanted to say is that tariffs, simply, won't work for the US. To strenghten the state and salvage the imperial capabilities the US would have to put an end to the ease with which the capitalists can move their loot to other countries. But to do so would break the tribute system the empire depends on. And to quit the empire would put an end to the liberal ease to do ecconiomic hit-and-runs.
That is why US politics has been without a proposed solution for known structural problems. There must be people who see them. There is just to way to fix one thing without blowing the other. And everybody in a position of power has been in either the capitalist caste or the imperial caste. Each caste knows it's running out of time but can't save itself by sacrifing the other. A change can't come from these two groups.
