So, one of the AI's declares war and attacks. I barely defeat his stack, and he offers a cease fire, he waits one turn and declares war again and attacks. I defeat his second stack, he offers cease fire, waits a turn and the declares war and attacks again, and then proceeds to go through this cycle two more times in a row before I save and shut down for the night.

It's a well known stategy. Offer a cease fire and wait a sufficient amount of time so that your enemy lets his guard down, and then attack.

But what the AI was doing was ridiculous. First you need to wait more than one turn to allow the opponent time to let his guard down, and second, the strategy only works once. Trying it 4 times in a row is just stupid. Sure I accepted the cease fires, but I never stopped building units....
