Why famous admirals could slow, but not stop, postwar cuts

Would Fisher and a deeper group of prominent admirals protect the Royal Navy after the war?

They could slow the pruning by giving the Navy prominent advocates, but they would not prevent a postwar reduction.

Major naval figures could give the service stronger advocates during postwar retrenchment. Their names and standing might help protect the Navy politically, although the Royal Navy would still be pruned. The likely difference is a slower drawdown rather than preservation of its full wartime size.
