Please add "invasion" with separate option and not only for the mayor.

The fact that you can only invade with the main nations and not with the other small ones is wrong. Especially in WW2" where there was a lot of conquest of micro nations to increase territories etc.
Beyond that, don't limit the "invasion" only if the relationship between nations is below 0, but always (because several nations have done this in WW1 and WW2 multiple time)
And obviously if you attack a nation when you're positive obviously the other nation is less reactive and therefore easier to conquer, obviously this will lower all the relationships with other nations that will see you as traitors.

Another thing, get rid of this "Dissolving" so fast, nations don't surrender that easily and it's never happened (where have you ever seen a nation dissolving during WW2) nations fight to the end and until it's completely conquered or he surrenders paying the cost.
Dissolving is unreal and not very credible nonsense, at most it changes the regime/government, but stay, so please remove Dissolving.

Having WW2 without the aircraft carriers, is WW2 without arms. Carriers were essential in WW2.

The devs have ruled out carrier from the start. I think this is fair, since the game is literally named after the dreadnought era. I would enjoy a carrier DLC if they fixed the main game, but it certainly is not neccesary.

The inability to easily invade minors definitely needs to be fixed, however.
