After a long war with the Persians that cost me a fortune to get out of, I'm afraid of them and the neighboring Aztecs until I get my feet back under me. I manage to convince Japan to sign an MPP. Two turns later England declares war on Japan so I'm forced to as well. Now I'm in no position to start sending units anywhere and I'm not going to be any help to Japan. Does this get noted by the AI somehow? Does it hurt your reputation to agree to an MPP and then not do anything when war breaks out?
