Our POD: After the German fleet is scuttled at Scappa Flow, Woodrow Wilson concludes that it was done with British connivance to deprive the other belligerents the fruits of their victory. He convinces France and Italy to send a joint ultimatum demanding that the British turn over half of their fleet to make up for the lost German ships. Britain, of course, refuses and is backed by Japan. War erupts
The Questions:
How does the fighting go?
I think the opening moves for the Americans/French/Italians would include seizing all British merchant ships in their ports and an American invasion of Canada. They would adopt the German strategy of starve Britain into surrender.
For the British and the Japanese, they try to isolate parts of the enemy fleets and sink them piecemeal. And this is coupled with a Japanese invasion of the Philippines.
How do the other powers react? Is there a sense that the Americans will win and now is the time to gang tackle the British Empire (Spain in Gibraltar, Guatemala in Belize and Argentina in the Falklands for example) ?
