IMO the chaos is the point.
If Europe and Asia are allowed to integrate economically, if Chinese tech and Russian fuel can easily reach Western Europe by land, then the US is finished as a superpower. Its naval superiority no longer will let it choke off the most important global trade. Its location turns from an oasis into a backwater. It became a superpower in the first place during the century of most intense fighting in Europe and Asia, and it needs the violence to continue.
