Honestly, I like unification of the British Fleet in SZ 30 with 1 Infantry from India. This makes it financially worse for Japan to attack than for England to be wiped out, strategically worse for Japan to attack (since they’ll lose their air force and have to leave Pearl unattacked maybe even not take China’s fighter out) than for England to be wiped out (all those ships are generally dead by UK 2 anyway, so what have you lost?) BUT
it really tempts Japan to try! Furthermore, form here, you can hit E. Indies with 4 Infantry, Fighter if Japan leaves you alone, or you can hit Egypt or you can just dump the infantry in S. Africa to bolster the defenses there.
Furthermore, if you build an IC in S. Africa (which negates the risk of losing Africa and thus your paycheck and allows you to stay in the upper twenties, lower 30s) you can be a relatively annoying pain in the butt. (Once Africa is secure, you can always dump a submarine or two in S. Africa making SZ 34 a threatened zone if you want too. Or at least pose the risk of doing so if you don’t want too.)
if I had to attack the japanese iwth England, I’d go Destroyer/Carrier to SZ 59; Fighter, Submarine to SZ 45 and land the fighter in SZ 52. I’ve seen quite a number of Japanese attacks on SZ 52 go south because of that extra fighter.
