What if USA sent 1 division to invade okinawa in 1945

If the USA had sent only one division to invade Okinawa in 1945, it is likely that the invasion would have failed. The Battle of Okinawa was one of the bloodiest battles of World War II, with heavy casualties on both sides. The Japanese had heavily fortified the island with underground tunnels and bunkers, making it difficult for the American troops to advance.

One division would not have been enough to conquer the island, and the Japanese would have had a significant advantage in defending their territory. The USA would have needed to commit more troops and resources to the invasion to have a chance of success.

Furthermore, Okinawa was strategically important for the Allied forces as it served as a launching point for the planned invasion of Japan. If the invasion of Okinawa had failed, it could have delayed or even derailed the planned invasion of Japan, which would have prolonged the war and resulted in more casualties on both sides.

In short, sending only one division to invade Okinawa in 1945 would have been a strategic mistake, and it is unlikely that the invasion would have been successful
