This is a classical problem. In theory it works when majority of the players work together and move in same direction, however everyone being opportunistic here makes in infeasible from long term perspective. Europe itself is in a difficult stage, its dealing with Russia on one end, has trust issues with China and now the its long term partner has gone rouge. The result of all this would be a mandate to be self sufficient aka anti-globalization
That multipolar world mandate you mentioned is already here today. That was the outcome of the actions of this US federal administration. Trust and cooperation is done for a half decade or more. The world can’t trust this administration for the remainder of the administration, and they can’t trust the US electorate to elect adults for the next administration. Countries can either accept it and take action to manage their risk (redirect investment to continue to decouple, trade deals with rational counterparties) to attempt to achieve a favorable outcome, or not and experience the potential natural consequences.
