Hi Reivaj
I will start to say that a 100 factors will influence your strategy. Mostly optional rules and how many sets you are playing with (PIF,ASA etc..) Thus there is no right answer to your question, just general advice.
1. The belgian units are going to disappear soon. Brussles has been conquered, so at the end of the turn the units will surender and disapear.
2. Your most vulnerable hex is the hex se of Lille. 2 german stacks can attack it and blitz an additional hex. Thus your defense should be very strong there. Also a 2. line of backup would be nice. The 5-2 mil would be nice to have as a 2. line defense in the hex ne of paris.
3. Your defense of italy is too strong compared to the defense of germany. You do not need the fighter down there. As Shannon mentioned the lyon mil is also not needed. The hex nw of grazziani does not need to be defended by 2 corps.
4. Paris needs a unit. Otherwise germany will be able to paradrop a unit into paris.
5. Relax, you are doomed anyway, so enjoy the game and dont feel too bad when germany wins
