Unhistoric? You get 500 MP for DOW against low countries but you get to decide when (as long as you are already at war with the allies). So how is that unhistoric? It seems to me the DLC is rewarding you to pllay more historically.
I thought that if you DOWed any of the nations in the operation techs before they were researched you missed out on the effect even if you researched them later on? If you can research the operations and get the effect even after you have overrun the nation in question fine but still.
In any case how would Germany get access to more recruits just because they attack another nation? (Excluding foreign SS recrutiments which are not covered by the operations.) I find it unrealistic that you would get access to 500.000 recruits just because you attack a certain nation.
