Again' I'm referring to interwar RN support of Britain's Pacific territory in reply to...
Once hostilities commenced, many British battleships entered Pacific waters. HMS Prince of Wales arrives at Singapore on Dec 4th, but did not venture in the Pacific (and only just, by entering the Gulf of Thailand) until hostilities commenced. Others got further into the Pacific, including HMS Anson arriving at Hong Kong in August 1945 to oversee Japan's surrender, and I believe the first RN battleship to visit Hong Kong since before the First World War. Which is my point, even during the European peace before Munich in 1938 or even the Remilitarization of the Rhineland in 1936, Britain failed to deploy any of its battleships or fast fleet carriers to remind Japan that Britain cares about the Pacific.
While I can't can't find any British battleships or fleet carriers in the Pacific, the PTO did get two RN battlecruisers in 1923-24, but when you look
at the map you see that Britain took great care not to come anywhere close to Japanese territory. HMS Hood and Repulse stayed in the Indian Ocean, heading dead south from Singapore, around Australia, to enter the Pacific near Adelaide on Australia's south coast. Then they headed northeast straight for Hawaii and Vancouver, avoiding any notion of waving the flag to Japan. HMS Hood and Repulse should have gone to Hong Kong after Singapore, then the British concession in Shanghai, and then sailed south to PNG and Australia. Britain spent the 1920s afraid to offend Japan, and declined to forward deploy its battleships or fast fleet carriers to the Pacific (i.e. Japan's backyard, not the I/O) when European circumstances allowed for it.
