Well, if two leaders decided you are a threat to humanity maybe they have a point.
Or perhaps they are not serious war mongers because they both respect an agreement and helping their friend.
It also works the other way around. If you can find a civ to support you you in your planned war you will get less penalty.
It does mean, though, that together you form a more important body of opinion than if you acted alone, thus you can lean more effectively on the others in how they view your actions.Just because you're doing it together doesn't mean you have a point.
After all, Nazi Germany and Japan should get less warmonger penalty because they declared war on the USA together.
No. That's not how it works. Just because you're doing it together doesn't mean you have a point. It only means you're both a dirty warmonger.
Either it's ancient era and I don't mind, It's only me and other civ on the landmass or I have a better CB.It's quite easy for you to joint war, I really have no idea why people surprise war
Well it isn't easy for me. I need to find an AI that both hates my target and does not dislike me. It happens , but it ain't everytime either. Yet again , I'm not a pro at managing my diplomacy I guess.It's quite easy for you to joint war, I really have no idea why people surprise war
