IWO JIMA AND OKINAWA
After securing the central Pacific region, the US targets the Ryukyu and Bonin Islands, which are in close proximity to mainland Japan.
The Battles of Iwo Jima (19 February – 26 March) and Okinawa (1 April
– 22 June) are incredibly costly for the US Marines, and the value of their occupation is later called into question.
