I don't want to be a cock-block - and it's probably not even in my interests so I probably won't do anything about it, in terms of military action - but whatever happened to the treaty that called for peaceful relations with German states? Unless you pull some more trickery to justify forceful annexation, it's not going to look very peaceful when Prussia steamrolls the countries it (and Austria) swore to protect.
