Phase 2 of invasions is proceeding, with phase 3 developing. IE landings have taken place at Rabaul, in Java, and Sumatra. Transports are underway to land substantial forces in Siam, for a push on Burma/India.
Naval high command lobbied hard for a change in Phase 2, or rather an addition: an invasion of the Philippines. Clark air base in particular, with bombers capable of hindering traffic to Burma, Singapore, Dutch East Indies, had to be taken out. So a landing was made on Luzon. US troops are fighting hard to hold Manila, but Clark air base has been taken.
