Build 2 Armies and Go Fight Germany! No, no no no no no no. This is the absolute LAST thing to do at this point. Before taking ANY action against Germany, you MUST consolidate your position. Sure, you can do a lot of damage to Germany, but while your forces cross that neutral ground of Tyrol/Bohemia/Galicia/Silesia, Italy and Turkey are going to have a field day in your rear. And why not? You may well get to Berlin and Kiel -- but they'll be the only centers you own when you get there! Heck, even if you do manage to hold on down in the south, it will be at the expense of the units it would take to do serious harm to Germany -- and then who is the big winner? England, that's right!
This is a very different situation than in our first examples. There, we had a fairly secure position, and we gained an ally as we turned our coat. Here, we've just stabbed Russia, then Turkey, then Italy -- not one of them is likely to forget that while you go and fight Germany!
