I know there is an outcry about the tab that seems to indicate you can trade provinces like in Vicky, but it is very logical and did happen in the WWII timeframe.
For example in the real war, when the USSR invaded Manchuria after declaring war on Japan, they handed it back after the war was over to China (methinks they did stick around and made damn sure that the Chinese Communists had control there).
Yugoslavia also comes to mind. Germany did most of the grunt work of the invasion but handed some of terriority to the Italians afterwards.
In HoI1, this was not possible even when they added the "liberate" option (C.O.R.E. did have quite a few events to address this though).
It would be logical if you could split up or at least negotiate with your allies on provinces that you have captured.
Ever have your units invading a province and one of your allies units arrive first from one of their adjacent properties and your massive force shows up and the enemey instantly retreats giving your Ally control of the province?
It was quite annoying and the only thing you could really do to gain control of it for yourself was to vacate the province and hope the enemy retakes it and then you reinvade (at that point I would be demanding military control over my Ally's units).
Now I don't see that Allies would trade off National provinces with each other and the AI and the players should not be able to "sell off" home provinces (like Germany selling Berlin to Italy), but it would be also logical if you could include threat of force in province trade.
Instead of having the "Danzig or War", the player (or the AI) should be able to send a diplomatic message to Poland in the trade screen showing:
You Give = Danzig
And will give in return = We won't declare war on you
If the player or AI of Poland rejects this then perhaps the nations would be in an automatic state of war.
The AI should have the knowledge to know that some provinces are worth going to war for and some are not, like Russia just waltzing into the Batlic states and Germany into Austria.
And this level of resistance would be based on the country asking since Austria would be more likely to give provinces (even all of them) to Germany, but would 100% refuse to hand over anything to Italy.
I forsee this as a way to make it unneeded to hard code HoI events to specific dates since it would give flexibility to do this at any given time.
This could also be used for "make your own bitter peace events". Instead of trying to capture specific pronvinces in the USSR hoping that the Bitter Peace Event will kick in, you could demand territory for peace and based on how long the war has gone on our, how many units you have lost, how much territory you have lost, and the current disent level.
Most smaller nations should be apt to refuse this and should not be allowed if say you've only been at war for less than a year (or depending on the nations will to resist).
Personally, I've always wanted to play as the USSR and declare war on Nat China in 1937 before Japan does and then hand their provinces over to Com China and bring them into a gigantic Commintern alliance. Just invading Nat China and annexing them did me little good since I could never take advantage of their massive manpower gains since their provinces weren't my National ones.
