One only needs to look at the spiral leading to both world wars to see that there is absolutely a good reason to communicate in good faith.
Tragedy of the commons right here.

Yes, in times of war the truth and with it good faith communication is one of the first things to go. This is a symptom, not a cause of war.
The view that every conflict can be solved by good faith communication in a for both sides acceptable manner is insane.
If one side wants to murder all people with a certain intrinsic attribute be it race, sexual orientation or whatever and the other side does not want to be murdered, there is no compromise to be made. The people of the first group will never engage in good faith with the later group that they view as subhuman. Any attempt to establish good faith communication will only HURT the later group.
