Step-by-step explanation:
The Americans used a military tactic called 'island hopping' in the Pacific Theater during World War II to fight against Japan.
This tactic involved the U.S. forces capturing strategic islands from Japan, bypassing the strongest ones, but seizing those capable of holding airfields to continue pushing Japan out of the region. By doing so, the U.S. forces were able to gradually move closer to Japan, slowly weakening the Japanese hold on the Pacific.
