There isn’t going to be a war with China.
It is too late to stop China’s rise, and a hot war with China will trigger the end of human civilization within an hour.
Both the US and China are dealing with their own internal contradictions and cannot afford to keep the animosity going for too long. What’s most likely to happen is a renewed status quo, with new boundaries established, after Europe and the Global South have been properly harvested.
In other words, the US and China will be the big winners in this new global reconfiguration.
The principal contradiction for the US is mostly internal, in that its persistent trade deficit strategy has caused led to its own deindustrialization and the disenfranchisement of its own working class.
The surge in populism after 2008 GFC prompted the US capitalist class to react, and Trump has chosen to reduce the trade deficit with China and the world as a means of resolving this contradiction, most likely because these are the executive powers conferred to him as the President and the strategy does not require extensive approval from the Congress.
Besides, China has shown no interest in challenging the dollar, and has in fact been the greatest beneficiary of the dollar hegemony. If you think about it, while only the American bourgeoisie benefited from the dollar hegemony and not its working class, Chinese workers have at least benefited just from the US consumers persistently buying their goods, even with the exploitation going on.
More importantly, the US is not interested in re-industrialization despite what Trump says.
First, the American capitalist class does not want to deal with giving workers the leverage that will happen when the country re-industrialize (that’s the whole point of exporting its own manufacturing capacity to the developing world).
And second, despite talks about re-industrialization, the US has yet to announce its industrial policy. This shows that whatever Trump says, it’s not serious.
Besides, who’s going to build the supply chain for the US if not China? It is far more likely that Trump’s global tariffs are a means to engineer recessions in the Global South exporter countries, prompting a harvest by American finance capitalism. If the US plays its cards right, it will be able to transition the primary form of dollar export from running persistent trade deficit to exporting dollar in the form of foreign investments and IMF bailout loans - most crucially, it preserves dollar hegemony and reduces trade deficit while allowing the US to reshape the global supply chain to its interests.
The true challenger to American finance capitalism is the euro. This is being taken care of with the Ukraine War and the Europeans will be properly disciplined. And it seems increasingly likely, as Yanis Varoufakis has been predicting, Europe will end up being the one to purchase American goods to reduce America’s trade deficit (euro will appreciate and Europe will deindustrialize in the process).
