The Kaiser was a big talker. There’s no way Germany could match Britain’s Navy, not in a thousand years.
Why not? Germany surpassed the UK industrially and economically during the 1880s. Building a navy surpassing the Royal Navy certainly was within their capabilities. Even one that was slightly smaller than the Royal Navy presented an existential threat to the UK because they could concentrate almost all of it in the North Sea wheras Britain had to spread it out to protect the Empire.
