Pretty sure the agreement was the other way around.
The other thing is that after yet another one of British Admiral Pound’s disasters, the sinking of Prince of Wales and Repulse off what is now Malaysia, the British didn’t *have* anything they could risk in the Pacific so any agreement would have been moot then.
I thought so, too, but I believe I have it right.
The British really wanted to be sure we were as involved as possible in the Atlantic.
The British were also quite concerned with Singapore.
I always wondered what the Japanese Navy did after Pearl Harbor?
They sailed into the Indian Ocean and scared Churchill something fierce.
