I agree. I would argue that Pax Americana has been pretty great for even the USA's supposed "arch enemies." My gut feeling is that everyone loved that stability, whether friend or foe, and the fact that it's now gone will mess everyone up.
I am biased here, but I look forward to the next century of Pax Europa. This is the only way forward.
Europe isn't playing aggressively enough or really doing enough to innovate. China is in a position to reap a huge windfall from Trump putting the US in the dumpster. China will bring Europe into the fold with the promise of gradual reforms, and they'll win the global south with soft power and trade agreements.
My fear is that Trump sees America's position eroding quickly relative to China before his eyes and decides to do something an order of magnitude dumber than anything he's done before.
