No one is secretly hoping to get a good deal from Trump. Everyone expects Trump to leave office at the end of his term and the precedent has now been set that the USA cannot be trusted to stand by any deals. Everyone is having to do the math of what to do about America's military because its economy is becoming less and less relevant by the month. When the only thing stopping economic disruption is tradition, and you actively destroy the tradition of stability, no one gets to make long term plans that involve economically stable relationships.

The US makes almost nothing. The vast majority of its GDP is artificially created markets involving intellectual property, military arms, insurance, finance, and the massive service industries that have been built around these industries and around navigating US government bureaucracy. There are only a handful of reasons why anyone cares about the USA:

1. Violence. This is the biggest one that everyone needs to manage.
2. Finance. Everyone's neoliberal system depends on the US and UK financial system. As long as they are coupled to it via dollar-denominated securities and instruments, the US is capable of crashing anyone's economy.
3. Consumption. The US consumer market gives people places to sell their shit and make money.
4. Oil. The US has an outsized influence on oil and has the ability to ruin most economies through that influence.

Speed run these 4.

Number 1 - I claim this is the only thing the US has keeping its hegemony relevant at every single turn. The rest can all be obviated.

Number 2 - this one is the one that Europe is fucked by. They can't fix this without aligning with BRICS and specifically China and Russia. That's because China and Russia are aware that the 3 pillars of their national liberation are military security against the US, domestic production with strong trading partners, and the ability to decouple from the US dollar. They are actively navigating the process of decoupling from the dollar and Europe will have to join them or be completely dominated by US financial institutions.

Number 3 - the US consumer market is utterly collapsing and has been for decades. The contradiction is very far advanced at this point, with average Americans putting medical costs on 17% interest credit cards. For decades the only reason the US remained a strong consumer market was because of the unfettering of debt and usury domestically. This is running its course. There is no real consumer economy that isn't 100% predicated on debt, and there is no debt that isn't 100% predicated on the dominance of US finance capital globally, and there is no globally dominant US finance capital without violence.

Number 4 - Europe is fucked. Their internal contradictions have reached their end stage. The only way they could continue their existence this long was through colonialism, and when the USA took over colonialism from European powers, it found that a distinct form of neocolonialism could be turned against them through finance capital and dollar hegemony. This form of neocolonialism didn't extract from European land, that was alread exhausted before the US rose to power. Instead, this form of neocolonialism was an extraction from the people. NATO is a tribute system to the US. Greece's dismemberment by German financiers was an echo of what US finance capital has been doing to the 3rd world for a century. The EU is trapped by its own unsustainable social relations and decoupling from the USA means social collapse into chaos and civil war between socialism and barbarism, a war that the US will enter on the side of barbarism. All the US has to do is cut off their supply of energy, and they already did a doozie with Nord Stream 2.

It all comes down to material violence, realpolitik not ideology. It's not because everyone's a neoliberal that they're acting like this. They're acting like neoliberals because the material conditions are requiring this behavior. For the European leaders, abandoning neoliberalism will result in dramatic violence and social collapse. For China, abandoning neoliberalism will accelerate the West's movement to world war.

You've got base and superstructure inverted.
