(C) Anaconda plan
(D) blockade
EXPLANATIONS BELOW
Concept note-1: -Leapfrogging would allow the United States forces to reach Japan quickly and not expend the time, manpower, and supplies to capture every Japanese-held island on the way. It would give the Allies the advantage of surprise and keep the Japanese off balance. The overall leapfrogging strategy would involve two prongs.
Concept note-2: -The US “island hopping” strategy targeted key islands and atolls to capture and equip with airstrips, bringing B-29 bombers within range of the enemy homeland, while hopping over strongly defended islands, cutting off supply lanes and leaving them to wither.
Concept note-3: -The American strategy to defeat the Japanese was to island hop around Japan, not to attack their country directly but to take over all the islands around it and surround them and hopefully starve them to surrender. It was led General MacArthur and also Admiral Chester Nimitz.
Concept note-4: -The “island hopping” plan involved winning battles on Pacific islands to gain military bases and moving across the Pacific Ocean and closer to Japan. This strategy would span three years and would take U.S. forces in almost a full circle around the Pacific.
