Interconnectivity by trade before WW2 was very brittle, because everyone involved had to fend for their own trading routes. The pillar of today's globalisation is that big and middle powers don't have to roll their own security policy just to keep their own commerce running. The global naval hegemon has been doing that for them for decades now. The moment this goes away, we will suddenly see a whole lot of regional disputes popping up. "Safety" inspections for container ships of the competition or more blatant interference using drones. Once a precedent has been set of the US not stepping in, it can turn wild pretty fast.
