Blitzkrieg!!!
Well this happened a while ago so I'm going off memory. I was playing as Ghenghis Khan and had conquered the Japenese a couple turn ago. This gave me almost all of the west of pangea but their was a narrow strip of land preventing me from getting to the western sea and that was the Incas. I eventually declared war and marched in with tanks and infantry. While I was doing this Montezuma was preparing for war against me. I had 2 civs on my right border. Alexander and Victoria. Montezuma was behind Victoria and was capped off to the east by water and the north by Alex. Eventually he declared war on me for no reason. I didn't know where he was at the time and got worried about losing cities so I made peace with the Incas even though I could have conquered them easily. I found out they were behind Victoria so I made a open borders agreement with her and invaded Monty. Eventually I conquered all of his cities on the continint accept for some on a far off island. I didn't feel like makeing my navy after I haden't had a single boat. I made peace. The point of this thread is that Monty had no way of reaching me because he had no open borders with Victoria or Alex.
