What did the Philadelphines campaign reveal about japan whom the United States fought pacific during world war 11

The Philippine Campaign, in which the United States and the allies began to close the siege on Japan that would end with the Allied victory in the Pacific, ran from October 20, 1944 to September 2, 1945.

Despite the fact that the military campaign was a success, which culminated in the liberation of the Philippines and the total defeat of the Japanese forces, it left the Allied forces a lesson that influenced the subsequent decision not to invade Japan and launch the atomic bombs: just as it happened in Okinawa and Iwo Jima, the Japanese fought until the annihilation. Thus, during this campaign more than 300,000 Japanese died in battle, surviving only about 15,000. Battles like the one in Luzon, where more than 200,000 Japanese died, demonstrated to the allies that bending the Japanese forces would be an arduous task.
