In my current game, I want to conquer Persia for a couple of reasons. However, the world peace resolution has been passed, and I am a little afraid of the public response if I just waltz in and conquer. I tried everything to provoke him to declare on me (that lowers warmongering penalties, right?), but he won't bite. So I finally decided to bite the bullet and attack anyway - just to find out that he has a defensive pact with America. I am not scared militarily, but I got an idea - if I declare on America instead, how does the pact work? Do I declare technically on both civs, or do I declare only on America and then Persia declares on me, and I get to conquer their cities with less penalty? Sounds fishy, but one can hope, right?
