It's all just end game capitalism really.....
"Capitalism sows the seeds of it's own destruction." Karl Marx
Capitalism is in its global phase so naturally it is in late stage. You start to run into issues like needing imperialism to increase capital or exploiting more people to increase capital. With Trump looking to have some imperialist goals with expansion into Greenland or mineral rights in Ukraine it certainly seems like Marx was on the mark for the imperialist mechanism. With his tariff maneuvers is he looking to bring exploitation home? The system needs continuous growth to prop itself up if it intends to stay a capitalist system.
Currently he is battling with global tariffs, killing trust, destroying partnerships, and making nations decide how they move away from dependence on the US. He may pick up a few tariff deals which change the numbers meagerly between nations, but that will not be enough to increase capital as the tariffs between us and the nations we trade with were already pretty favorable.
So it makes you wonder, is it all about capitalism? I propose it is something more nefarious, something like a move to a more techno-fascist and neo-feudalist society in which the oligarchs leverage desperation for jobs with worse conditions and an overall lowering of the standard of living in the US with insane wealth consolidation by those already on the top. Historically, it was not that long ago where desperate men and women lined up outside of unsafe factories, meat processing plants, etc to get a poor paying and unsafe job. All while life expectancy was in the 40s in a large part do to living and work conditions.
When I am spouting my progressive ideals they are to oppose the exploitation mentioned above. I do not believe the model of perpetual consumption is sustainable therefore we need protections from capitalism when the time comes.
You may also be underestimating how much those two hate each other also.
Japan is not ignorant to the chinese ways, they know the implications of China getting hooks in you.
I think you have this one a bit backwards. China were victims of Japan cruelty in WW2 and it cost China 20 million people or so. Prior to that China was pretty isolated, and the Japanese incursion is one of the reasons China modernized. The other would be US companies looking to increase capital with exploitation. It has the unfortunate side effect of losing a lot of the US manufacturing base. China didn't do that to us though, US business magnates did with the help of normalized trade relations with China by the government started under Clinton but with talks going back into the 80s.
China hasn't really been actively scheming as much as companies saw an opportunity to make more money by using China, but now China is the enemy because while we used them to increase profit they naturally increased influence.
