I think in a way you've also hit the big point.
Firstly as Condottiere has said what fleets are the Germans stealing? Again This Germany isn't Nazi Germany with designs to conquer all of Europe, this is a Germany that wants it's place in the Established order recognized. Their not going to conquer the whole of France and use the whole of Europe's Fleets to take over Great Britain.
And this then rather ties into What Lord Oba has said, that again Germany are no better or worse than any of the other contemporary Imperial Power.
