The force and escalation problem in retaking Hong Kong

Could a combined Commonwealth fleet retake and hold Hong Kong?

It might launch the operation, but realistic success would require broader Five Eyes support and could trigger major or nuclear escalation with China.

A fully combined Commonwealth fleet and air group might launch an operation, but American support would still be needed for a credible chance of success. A Five Eyes coalition offers a more plausible concentration of naval, air, amphibious, and command resources. China would respond in force, creating an immediate question over whether the conflict could remain conventional. Hong Kong's people and skills matter more strategically than simply holding the land, so evacuation and economic consequences may be more important than territorial recapture.
