Being the Austrian, confronted with a Prussian scheme hatched without my input, ignored by Great Britain - more so, rebuffed by GB when requesting an alliance in Jan - what is there to do but conserve energy for the next few months?
Oops. Well you can decide to argue this out with your Prussian and British friends. Or you can conserve your energy for the next few months, after which Napoleon and 200,000 of his mates will be headed for Vienna to give you a pasting.
On the other hand, you can lose the first war (as either Austria or Prussia) and even the second one, and still be in with a chance. You don't need nearly as many VPs as France does -- he must keep coming after you and winning every time in order to win the game. One unconditional surrender and your job is made a bit more difficult. One unconditional surrender, especially early in the game, and France is history -- no chance of winning from there.
Anyway, it's going to be a learning experience for you both.
