Specialized American and general-purpose British cruisers

The Royal Navy's worldwide trade and imperial commitments left it little room to build separate cruiser types for scouting, fighting, and commerce protection. Its treaty cruisers therefore remained general-purpose designs, even when a class emphasized one role more strongly than another. The U.S. Navy could build more specialized reconnaissance cruisers and then evolve rapidly as the strategic situation changed, demonstrating an institution willing to learn. The cost appeared in 1940s combat: British 1920s cruisers still fit broad missions, while American 1920s scouts had to fight a war for which they had not been designed.
