Here we go, here is the Military History of the UK during WWII.

Destroyed in Malaya and Singapore, kicked out of Burma, retook Burma (half of which was troops from India), and the supported the US in the invasion of Okinawa without landing any troops.
I'm not saying these countries didn't take part; They did. But their contribution in the Pacific was even less than what the US did in Europe.
