This game is really too complex to allow AI to run the major powers. For sure, Russia, Britain, France and Austria should be player run; however, this does not mean you cannot play the game without a human opponent. Those of us who came to wargames before computers played many games versus ourselves, that is, we played all sides. So rather than becoming disappointed because the AI does not work as you hoped, play Britain and France.
This is truly a fun way to play games as it provides you better insight into all aspects of the game. Some players are concerned they might 'cheat.' But really, all you are doing exploring the 'what ifs' which is the primary delight of playing simulations. So it is ok to see what happens if France does something silly. But I suspect you will keep trying to beat your other self.
This is a very rich game, just try out this other approach.
