Well, you need a stable government first. Right now Germany isn't doing too much. Don't worry, we can attack for you but Poland is the kind of country to refuse giving away Danzig to the strongest military in Europe which happens to also be a nuclear power - they're masters of bad decisions afterall. After not taking control of Russia a few centuries ago, not destroying Prussia and weakening Austria by allying the Ottomans - by not centralizing their government, become puppets of France, then being released as a buffer state, just to be invaded again - they find a way to deteriorate diplomatic relations with all of Europe.
FeelsBadMan. Make Germany Reich again.
