User: What was the turning point in the Pacific Theatre in WW2?
Assistant: The Battle of Midway in June of 1943 was most likely the turning point of the Pacific War.  Up until that point, the Japanese held the initiative and momentum.  When they lost 4 carriers and precious pilots and planes during the battle, they were significantly weakened and were never able to regain the initiative but instead spent most of rest of the war on the defensive.
