@TN: The sad thing is that you and England didn't work out a truly concrete plan until after the Burgundy misunderstanding. And speaking of which, I just found another line that makes said understanding all the more surprising, which I never mentioned in-game. Right after your message about "I'll go with whatever method you think is best," I literally inform you "I'm going to move to Ruhr, Kiel, and Denmark."
I guess I had better be really explicit in the future, because it feels like our entire alliance fell apart because I did not slam the DMZ home. Either that, or you just happened to have a really off day.
@TB: For me, there was so much distrust because I was completely blindsided by France and England turning on me in F1901. It led me to conclude that I could trust neither of them unless they had _strong_ motivations to act in my favor. This led to me selling the Juggernaut to both of them, France's untrustworthiness to England, and England's hovering over our backs to France.
The problem, of course, is that my efforts effectively locked me into a Western Triple. My decision to eliminate Russia with England worked, in that it tightened bonds with England and got France completely off my back, but it also ensured that England would hold a superior position over me. This was compounded by the fact that I didn't trust France for a good half of the game, and did everything I could to limit his builds (mostly through English pressure and peace with Italy).
By the time things were patched up with France, I still hadn't had an excuse to build a second fleet, and most French units were tied up in the south. This made an attack on England unlikely, unless perhaps England left himself vulnerable to me in order to stab France first. I subtly encouraged this a few times, but I never strongly pushed it because I didn't trust England not to simply tell France about it, and because the whole thing would have been highly risky anyway.
Similarly, I never trusted England enough to eliminate France (though it turns out that the EG alliance in the late game was far stronger than I realized). This was primarily a matter of positioning, as England would profit by far the most from eliminating France, and there was little guarantee that EA wouldn't simply pincer me afterward.
As for Austria, I never trusted EF enough to throw all my forces at him. He was my insurance plan in case they decided to cut me out of the draw.
So, basically, my entire game after 1901 was an intricate dance to avoid my own demise. It worked, but the systems of fear, alliance, and positioning worked so well that even I couldn't figure out a way to break out of it profitably.
