1. when you capture certain (main) bases, then main oponent surrender automaticaly, removing all his units, leaving only ones outide enemy range - e.q. if japanese capture all main philipinese cities, then philipinese surrender, with adding all philipene bases to japanese ( I hate conquering small, empty bases). Onlyest philipenese units which will continue fight will be outide philipenese main island.
2. wars start only between combatants - for this insired me this thread - tm.asp?m=2547903 - so, if plaers decide to ignore PH (and philipines), then his have war only with europe + china, or can completly ignore (for certain time) all pacific completly with moto "kill all chinese first, then deal with rest".
Of course with corespondinh triggers - if japanese decide to conquer all china firstm, then it will not need mighty fleet

And it will brigh one nice feture too - I will LOVE to see on 8th. to see (historical) newspapers informing on japanese attack on PH and declaration of war

3. this will mainly for "fun" - like news informing about your side first ace (and pilot who will kill more than 10,20,30..etc), infos of great/important war events (e.q. conquring PH

4. "forced" recombining - it will merge (if posible) all subunits of air wing to main (can work for LCU too) , if adding of planes is not posible (different type), then only pilots are added. Every non-mergeable detachment of planes/pilots is send to pool.
For now, it is all. Others ideas are welcomed.
