I mean, if I was a policymaker in the EU:

• do our absolute goddamn best to SIGNIFICANTLY strengthen ties with India, Japan, SK, and other major friendly-ish players in APAC. Ultimate goal: mutual defense pacts + strategic defense partnerships
• have Very Serious Strategic Talks with SK; tell them to stop taking orders, or at least gouge the fuck out of, US companies, in exchange for becoming a core partner in the build out of the EU military expansion (see: Poland; ctrl+c, ctrl+v across Europe)
• nut up and seriously support Ukraine - potentially just completely taking over strategic air defense from, let’s say, 100km from the front lines, freeing up the UAF to focus on offensive efforts
• have Very Serious Strategic Talks with Taiwan; in concert with points one and three (which seriously increase credibility), do their best to become their defense guarantor, as the carrot; threaten to 100% cut them off from ASML if they dig in their heels, as the stick. Note: ASML are the only guys who make the EUV litho machines that are required for bleeding edge chips.
• get EU countries to start seriously building out advanced chip fabs to compete with TSMC as an emergency industrial program

That’s a strategy that I think would help age EU and its strategic partners in Asia effectively become a meaningful superpower.
