Was Iwo Jima and important battle in the Pacific Theatre of Operations in WWII?

Iwo Jima was a major strategic island for the war in the pacific in WWII because, the airfield was vital to bombing raids on mainland Japan, it is apart of the Japanese mainland and a pivotal moment on Iwo Jima helped change the moral and war effort towards the end of WWII. The airfield on Iwo Jima was extremely important because it was so close to mainland Japan, that the Army Air Corps (at the time), could make out longer bombing raids and hit more vital targets on Japan and it is where the Enola Gay took off to drop the first of two atomic bombs on Japan. Iwo Jima, even though and island, was and still is apart of mainland Japan, this was the first piece of Japanese territory the United States had conquered which showed how close the US Marine Corps was to potentially reaching mainland Japan. The moral of the war was getting low at this point in 1945, but when six US Marines were photographed by Joe Rosenthal on top of Mt. Suribachi raising the American flag, it instilled hope in the people that America was still in the fight and that the war was still in favor of the United States. The photograph helped with boosting War Bond drives to gain money for the war effort and keep the boys on the front lines clothed, fed and steady on ammunition.
