So I didnt need to, but I kept the Iridium around as 'pets' while I am finishing off the Yor. I got an Alliance with the Iridium as well. I also had Military Alliance, but I still havent seen that do ANYTHING.
So, the Yor asked for peace, I accepted. I then started to bump up my influence, which pissed off the Yor, and they pre-emptively attacked me (they even said they shouldnt, but it was a matter of survival, haha). My "allies" didnt do ANYTHING. They didnt declare war on the Yor. In diplomacy, no option to ASK them to declare war. I actually had to break our alliance treaty, and then 'bribe' them to do so. I didnt need them of course, just playing around with diplomacy, when I may need it on harder levels.
So, what gives? This doesnt sound right at all.
