@Jennifer:
You can add to that that the Bomber from E. USA can hit SZ 60, a little known fact in the AAR community.
So you have a japan that’s primed to be crippled.  Though, if you go full KJF, I highly recommend forgoing the Borneo invasion and getting an IC in India.
Another little known one is that SZ61 is not as safe as Japan may believe.
If Russia has staged 6 inf in buryatia and Japan opts to leave manchuria to Russia (or Russia is set up to hit it on R2), a UK bomber from as far away as caucasus, Moscow or even crazy spots like Trans-jordan or Italian East Africa.
You could even get a little goofy and land the UK ftrs from London in West canada to follow up that US1 attack(ftr, bmr) on SZ60
