Moot points kcdzim.
If Moscow falls and Japan hasn’t even attacked Russia yet… game is over anyway, regardless of the 12 IPC. More after than not, you’re going to forget about the bonus when it gets to Russia’s turn, so it’s best to do it after you get attacked !!
It’s not a moot point. According to the national objective rule YOU described here’s the predicament:
Germany is going to attack and potentially take Moscow next round. Japan knows this, and attacks. According to you, Russia would immediately collect 12 IPCs. Germany attacks, conquers and receives that 12 IPCs. That is not the intent of the rules (because this ended up being common when the IPC bonus was introduced and was worded as you described).
That’s an exploit, and it’s specifically written such that you cannot do that. As for forgetting it, any reasonably competant gaming group will set aside the money for collection at start of turn - not simply forget to grab the money at all. And more often than not, when either Russia or Japan attacks each other, they’re probably not likely to be in a position to lose their capital next round, so yes, in theory you could just immediately add it to your pool.
However, in the event that they are going to lose their capital, by letter of the law, it’s not part of the nation’s IPC pool until start of their next turn. So it’s not an immediate bonus provided to the conquerer. In fact, if they lose their capital, they don’t collect that objective at all, as nations that have lost their capital cannot collect any income (only capture).
No points of interest declaring war on France, the Destroyer over near Africa takes to long to get over to be a problem with the rules.
As Hobbes mentioned, New Hebrides. But also, the French destroyer may be moved to India or be used as a potential block against Japan. By declaring war, it can no longer move through a seazone with a japanese ship, and it could be attacked alone if it ends a turn in a seazone with a british ship. Just because it’s not likely to happen doesn’t mean it can’t.
