Why British and American interwar naval economies differed

How did British and American political attitudes toward naval spending differ in the interwar years?

Britain often spent reluctantly when it believed it had to, whereas the United States was more likely to leave even treaty-permitted construction unfunded.

Both governments wanted economy, but Britain was more willing to spend when strategic requirements demanded it. Treaty allowances expose the difference: Britain often funded ships it was permitted to build, while the United States Congress frequently left authorized naval tonnage unrealized. Similar pressure to save money produced different fleets.
