When will the Soviet Union and Japan be placed in war?

Highest I’ve seen without taking capitals is 60’s

actually the us can enter war if any territory in n. america is captured.

Ok after reading that I believe it cleared up all the questions I had.  It makes a whole lot more sense now.  Thanks for your help guys.

Yeah that would be hilarious to screw your teammates cause one forgot to bring beer over, which means as playing as the US I would buy infantry and anti aircraft guns to protect Alaska and my crab fishing grounds.

@Lozmoid:

So - I trust you pay for the upgrade during the Purchase & Repair Units phase, and then the upgrade actually takes place during the Mobilize New Units phase. Is this correct?

Yes.

@Lozmoid:

If this is correct, then I assume that the newly upgraded IC (now a Major Industrial Complex) cannot begin to mobilize its full quota of 10 units until the owning player’s next turn. Is that right? It can still only build 3 units during the turn in which it was upgraded. Please advise if I am wrong.

You are correct.

Since Japan has so many planes I find MI are really useful as bullet sponges. The planes provide mobile killing power, the MI mobile protection for the planes and occupation.

If US decides to build up in HAW seazone, your aircraft are useless for a complete round (or more). Because you can’t fight that seazone (6 spaces). As US player I would just sit tight, build up and move to Japan via a northern route. Or go to Indies via southern route (Australia). Or build up TR with loads of cargo to take out Carolines. For every fighter it costs Japan it costs an inf for US.

And I think it will be a very dull way to play, or am I mistaken?

I guess Manchuria will be also an option in global game if non-agression pact is not the game
