Realistically, England starts with 3 Fighters. You have to assume you’ll lose Egypt and the fighter there to the Germans. It’s also safe to assume that Norway will be empty or very close to empty. (That’s the problem with debating the round 1 of a nation after Russia, you have nothing in concrete!)
If you go KJF, you have to have an IC in India. Not to mention it’s strategic location near the front, close to high value targets like FIC, Borneo, Philippines and East Indies is the fact you get a free AA Gun to go with it!
If you go KGF, I highly recommend a full scale invasion of Algeria followed up by American reinforcements, followed the next round with a taking of Libya with more forces moved from England to Algeira. This gives England 2 more IPC to offset losses.
A fleet idea I’ve seen work a few times is to hit the British transport with your carrier and destroyer, amphibiously attack Borneo with 2 inf from India, amphibiously attack New guinea with 2 inf from Australia, send a fighter and submarine to the solomons to kill the enemy sub and land the fighter in SZ 52.
This, in effect, destroyes Japan’s ability to fight for a few rounds. Followed up with ICs in India on UK2 and ICs in Sinkiang US1 and China US2 and pressure from Russia with light forces (just enough to keep Sink from falling long enough for America to have a stack there) and you can effectively neutralize Japan in 4 rounds.
