GB even supported Hitler's breaking of the Treaty of Versailles with the Anglo-German Naval Treaty, 1935.
Germany's request for the Sudetenland also bypassed the League and went straight to Britain, France and Italy who appeased him.

BR, FR and Italy continued to appease him.
He continued to do whatever he liked and the League's input was irrelevant.
