The United States Navy used the tactic of "island hopping" to fight the Japanese Imperial Navy in World War II. This was because the U.S. A) was preparing its forces to invade Japan via Korea in order to end the war early. B) relied on the Soviet Navy to advance on Japan from the north, capturing many of the other islands along the way. C) chose to focus on capturing smaller, more vulnerable islands in hope of cutting off heavily-fortified islands from key supply lines. D) focusing all of its naval power in the North Atlantic, North Sea, and Mediterranean Sea in hopes of breaking the Axis blockade of Europe.
