Decisive Darkness: What if Japan hadn't surrendered in 1945? by @The_Red
Stockade housing some of the thousands of captured soldiers in Okinawa, prior to their departure to mainland US, late 1945-1946
The Ryukyuan people were almost compared as the Hawaiians natives prior to the US annexation. They were almost considered as second citizens in Japan as many ethnic minorities in the US, with reports that some locals were even killed by Japanese soldiers went hearing the Ryukyuan language, thinking that said language was a sign of spies.
Unlike with the previous occupiers, the Ryukyuan could now express their language and culture prior to the Japanese annexation. While initially untrusted by the now rulling United States Military Government of the Ryukyu Islands, as they were most co-operative compared to the average japanese, the US would support both civilians and militia units. Outside of military bases, they would help in catching any Japanese fugitives and few holdouts still active in the island alongeside some American (and Commonwealth) forces send to help. To arm said militias, they were given mostly captured rifles and light machine guns, with handguns been US-made revolvers, and they part of said job is just to scout, spot and start the engagement, as the accompaning Allied forces would to most of the real dirty work.
While in some areas, many civilians were forced to leave their homes, the US (under the eye of the United Nations) gave them some housing homes to said civilians, to most part, help in their co-operation, preventing any rebellion cell to be form in the first place and to be seen as the "good guy" compared to their previous occupiers, and also to provide the Allies with "cheap labor". While to this day, the hoped independent Ryushu Islands is far, far away, they nonenless are considered in Washington D.C as American as a New Yorker or a Californian.
Last days of the Douglas SBD-5 Dauntless in US service, on VMSB-243, Philippines 1945
When the US Navy began receiving their first AD Skyraiders, AM Maulers and Kaiser-Fleetwings BTKs (plus SB2C-5 (and Canadian SBW-5) and -6 Helldivers), they relegated their stock of older Helldivers to the US Marines VMSB Groups (even the ones now onboard the "Marines Carriers" - a name given to escort carriers carrying the Marines Carrier Air Groups). In tears and cries, they have to said goodbye to their beloved Dauntless, the aircraft that in many Americans eyes, saved their bacon in early/mid-1942. But the aircrafts would still fight until the end of the war, now flying in the Philippines Army Air Corps, still bombing the few Japanese holdouts in their home country.
Giuseppe Garibaldi light cruiser in 1938
On the suggestion of its Ambassador to Washington, Alberto Tarchiani, Italy formanly declared war on Japan on 14 July 1945, with the sole purpose to persuade the Allies that Italy should be invited to the San Francisco Peace Conference, as a reward for its co-belligerence. However, the British Prime Minister Churchill and John Foster Dulles were against the idea. But with Clement Attlee running the British government, and the need to put more pressure against Japan, they abliged as long as Italy would follow up with military support.
The Kingdom of Italy, reluntantly, would ablige to this, but with a war weary population nearly bringing the government down, they were forced to ask for volunteers. With this, only a cruiser division (divided itself) and a transport squadron (flying Dakota III) were send to fight in the Indian Ocean, arriving in November 1945. The ships, two Duca degli Abruzzi-class light cruisers were used for combat duties (Combat Force - or CF), while Luigi Cadorna and Raimondo Montecuccoli (also light cruisers) were used as fast transports with self defense capabilies (Transport Force - TF - all ships are from the Condottieri-class cruiser, been sub-classes compared to its sisters).
The CF were to perform escort missions (many times with the TF unit), search and rescue and shore bombardment missions. In the latter part, they participated in both Operation Mailfist (the liberation of Singapore) and Operation Oboe 4 (invasion of Batavia, Java island). With them came a new addition: SOC Seagull's. While most navies were dropping the catapult in their ships, the Italians would still hold on to it up to the end of the war, and with their previous IMAM Ro.43 been harder to supply, they bought the closest biplane that the UN had: the Seagull, as the US Navy were replacing them with Seahawks and Columbia JL aircrafts. They (alongeside the Dakotas) also had a roundel equal to their Co-belligerent Air Force, but with the red removed, leaving only the green/white circles (similar to the British/Australian SEAC ones)
