So I played a game and my neighbor was Mao Zedong. I tried to remain friendly with him by having open borders and expanding my religion to him. Then out of no where, he declared war on me. I looked at our relationship and it said +2 for sharing the same religion and -3 this war has spoiled our relationship but he started the war so it couldn't be that. Is Mao Zedong known for attacking his friends for unknown reasons?
