I DOWed the Netherlands to puppet it. Portugal(sphere leader), UK, and Russia answered the call on their side, and USA/Mexico on mine(I used yesmen to make sure it would be a great war).
These were all the peace terms with Portugal and the UK...I took Finland, Karelia, and Western Ukraine from Russia, and puppeted the Dutch. I obviously used yesmen, but, in my defense, the US had occupied all of Canada, and I had occupied all of Britain and New Zealand. I would hope that the occupation of Britain is enough to rationally demand the release of South Africa and the freeing of minor provinces(British Guyana, Falklands, Ethiopia, Singapore, British Burma)
Next war, I'm, going for the release of Australia and the end of the British Raj
The results on the world map:
Not shown: I made Portugal release Djibouti to Ethiopia and Southern Tanzania to Zanzibar. In addition, I restored the Suez Canal from the UK to Egypt and gave Ethiopia her cores, which had been colonised by the Brits.
