landing a force to seize the island of Oahu

As we read in: The Japanese Thrust - Awaiting the First Blow

"Although some officers favoured landing a force to seize the island of Oahu, in which Pearl Harbour is situated, it was decided that there would not be enough transports for this purpose as well as for the southward move."


The questions could be asked what if?

If Japan controlled Pearl Harbour? No battle of the Coral Sea? No battle of Midway? No Guadalcanal? And New Guinea invaded soon after? Australia?

Or as we read in Japan's Decision for War

"Perhaps the major Japanese error was the decision to attack the United States at all. The strategic objectives of the Japanese lay in southeast Asia and if they had limited their attacks to British and Dutch territory the United States might not have entered the war."

So having decided to attack Pearl Harbour and then having missed the fuel storage and dry docks, and not landing a force on Oahu. They gained Malaya, and then the NEI, and Burma, and parts of PNG but lost the war.
