How complex would it be if diplomatic relations would influence recruitment abilities?
Details
When realm A is in war with realm B, in regions where peasants hate realm B recruits would have higher morale, and more recruits would be trained per day. Counter-effect is bellowed realm is attacked.
Of course, when realm is also in war with realm C, who is loved by some peasants, in such regions effect would balance each other.
It is only my assumption that it's not overly complex to code when there are already peasants' diplomatic mood in place for every region.
Benefits
It would add little more depth and complexity, and most importantly, it would put more weight on diplomacy in overall. That would not actually be revolutionary change, but just enhancement of existing "regional diplomacy" feature
