Exactly what it says. I remember once playing Kaiserreich as Russia, got event when I get chance to seize Crimea, I did, and Ukraine declared war on me over this, dragging entire mitteleuropa in. When they were fighting internationalle - with 99% of German armies in the western front, I was on outskirts of Berlin before I faced serious resistance. If I was Germany I would've rage quitted.
What will prevent one province minor from screwing huge coalition with declaring war on military-industrial giant? Lets say I play Bhutan or New Zealand, who is in Allies, and decide to DoW USA in 1940, just for lolz, why shouldn't UK be allowed to say: "yeah, we are ditching those lunatics", causing aforementioned OPM to be kicked out of alliance to face the giant alone? Effectively refuse call to arms.
When nonleader declares war, alliance leader gets to decide whether join (if refuses aggressor is kicked out of alliance, but not out of previous wars), and then other members are asked. If alliance leader declares war, members are asked directly - in both cases there are option simply not to press "Call to Arms".
If you allow countries to be allied, but not necessarily join each other at war in every single case, you could have Japan in Axis (since they were not at war with Soviets until 1945), and you would not have America automatically Dow Germany just because they got attacked by Japan, since they joined Allies. Germany could have an actual reason to DoW USA, for example they want to attack american convoys that go to British Isles, otherwise they couldn't starve UK into submission.
But for Christ sake, please no automatic war.
Because really guys, if I play Tannu Tuva, and DoW Japan, China and USA in 1941 while Germans already are few provinces away from Moscow, Stalin would just meekly say: "whatever you say dear...." and go to war on four fronts!?
