Why do we have 2 formally declare war, why can't you just start bombing and it's war. You have to "invade" or "Declare War" or attack one of their units. And lets say you "accidently" went on to their property, why can we not just say sorry and no war? Firaxis doesn't understand the difference between peace treaty and cease fire. in a cease fire, there's still a war, just no fighting. In a peace treaty the war is over. Plus why can only one side trade in a peace treaty. I recall that after the Mexican-American War, The U.S. got a set border and most of the American Southwest from Mexico and Mexico got payed some money.
