If warmongering in real world existed in the way it exists in this game, America would be denounced and attacked by half of the world after attacking second "minor civilisation" (Iraq, after Afganistan), and nobody would care about their economical connections with USA nor about 9/11 and Al - Quaeda.
Currently, I am radical - I would love total removal of entire warmonger penalty. Total and complete. We have it in this game since 2010, and it has been causing nothing but frustration, problems and dozen patches trying to improve that, but apparently this entire concept is wrong and should be simply removed (or changed into something more logical)... At least, "warmonger penalty" should disappear in the way it is depicted currently - "We were best buddies and fighting with this bastard was in our interest, but apparently we decided to completely irrationally attack YOU, you Hitler! Oh wait a minute, I will return to kick your butt after ending my own 25th war"
This is illogical, stupid, not realistic and extremely frustrating:
- warmonger penalty because of defensive war (IRL - USA would be denouced by half of the world, and Allies, because it captured cities of aggressive Japan which started the war...)
- warmonger penalty with best buddies (IRL - USA would be denounced by Great Britain, also in war with Japan but withour capturing this damn cities - because betraying your extremely powerful and loyal ally because of his war success with common enemy is so damn logical)
- warmonger penalty because of war absurdly long ago (IRL - Turkey would be hated by the entire world because of capturing Byzantium capital!)
- warmonger penalty because of conquering... the common foe (IRL - France after WWII immediately denounces USA because this warmongers captured the western Germany!)
- warmonger penalty because of fighting with warmonger!
Nope. I have mod which completely disables this entire crap. In my opinion, instead of WP we should have something making much more sense and much less frustration. For example, it should activate not after capturing damn one city somewhere in the jungle, but when certain civ is REAL menace to the world - for example, it captured few capitals and is definitely going for domination victory. But all that incredible hostility of dozen civs, hostility of the entire world, because of one war? With city - state? Come on.
