Yup, the middle powers have to organize and work together to avoid being chum. The economic power is there, and they can shift from purchasing US weaponry (thus paying US workers) into purchasing middle-power weaponry (thus paying middle-power workers). Car/truck plants can be repurposed, and if Ukraine's lesson is valid then smaller, portable weaponry is now the preferred solution. Cheaper, and the middle powers don't have huge investments in tanks and ships.
