Days of Infamy Background
After the First Sino-Japanese War in 1931, the Japanese decided that the Chinese weren't their enemy and decided to try to be on friendlier terms with China. Because of this, the OTL Second Sino-Japanese War would never happen and the Japanese would focus much more into a war with the Western nations, namely the United States.
The Japanese war planners realize that just an attack on the American Pacific Fleet would only lead to a war that the Japanese would not win, they decide that the best way would be to invade Hawaii and Alaska, and to destroy any remainders of the Pacific Fleet to force a peace treaty and to secure their dominance over the Pacific. On December 7th, the Japanese bombed Pearl Harbor, Hong Kong and invade Malaya and the Philippines. Hours after these events, the Japanese invasion of Hawaii begins. By February 1942, the invasion of Alaska also commences, followed by the Fall of Singapore. The American and Japanese fleets would meet face to face in the largest naval battle in history, on June 4, at the Battle of San Francisco.
All of these events would not only change the Pacific, as the OTL Europe-first would become Pacific-first instead.
