Why Britain prioritized the Army of the Rhine

Why did Britain prioritize the British Army of the Rhine over the Royal Navy during the Cold War?

Holding West Germany was politically decisive because the outcome there would shape the terms on which the conflict could end.

The speakers distinguish forces that physically survive to negotiate from forces whose early performance shapes the eventual settlement. If West Germany held, a return toward the status quo might remain possible; if it fell, the West would negotiate from a far worse position. Political credibility and alliance commitments therefore pushed resources toward the continental army even though maritime forces retained vital reinforcement and strategic roles.
