Why an Anglo-German naval treaty was politically implausible

Could Britain and Germany have negotiated a naval treaty before the First World War?

Not realistically: Britain distrusted Germany's naval challenge, Germany demanded recognition of its place in the sun, and neither side had the political maturity or shared assumptions needed for a durable settlement.

Britain saw a formerly close power turning into a direct strategic threat, while Germany wanted status and concessions that would acknowledge it as a leading world power. Even Britain's arrangements with France and Russia were understandings rather than a simple alliance template that could be copied.
