What is the big deal of declaring war here anyway? Everybody has
8 luxuries within distance 3 of the capital...!!
I don't think that war happiness will be a major factor in this game...
(And it's Monarch, so with a marketplace your cities can grow to size 22, before you need to raise the lux slider to 10%...)
You declared on both France and Germany. China, as your locked ally needs to do the same. That is standard practice.
Well, here I must disaggree. The thing is called "Mutual Protection Pact", and not "Mutual Agression Pact"...
And the way an MPP works in a standard game is like this: Iroquois and China are locked in an MPP and if nation X attacks Iroquois, then China will declare war on X. But not the other way around (if Iroquois attacks X, then China does
not need to declare on X). This is confirmed by the Civilopedia:
Furthermore, if any civilization attacks another nation that is part of a Locked Alliance, the attacker will find itself at war with all nations member to that Locked Alliance.
This is what happened here: Iroquois ("any civilization") attacked France ("another nation") and found itself at war with France and Germany ("all nations member to that Locked Alliance"). The Civilopedia doesn't say anything about the alliance partners of the attacker. Therefore, if indeed no Chinese units are inside French borders, then I have to support Ivan: there should be no reason for China to declare on France.
On the other hand: as I stated above, it is really
insignificant who declares on whom. If both sides played the game correctly, they should by now have enough luxes connected to run 0% lux rate --- and you can't drop it any lower than that, can you...
So please, Memento, just declare war, and get on with the game...
And for Cyc: I think, more urgent than resolving this question here should be getting a good "German Expeditionary Force" going...
