This week’s readings by Fearon, Schultz, Oneal & Russet, and Lebow mainly focus on war and peace theory from an international relations perspective.

In addition, states mostly fail to cooperate and choose to go to war under certain causal mechanisms that include misinterpretation of private information, and states’ incapability of keeping the deal. States revealing their private information to each other can bring peace, but mostly they all refuse not to share, due to mistrust. If USA and USSR trusted each other and were able to bargain, the Cold War would probably not occur. Also, this relates to
