Well, the Germans were quite terrible at predicting public opinion in other countries during both world wars.[0] So I won't use this as a precedence or an excellent example of your point.
In their defence, however, I'd argue that the American public was against intervention before Pearl Harbor. Still, should have been predicting that one as well.
Lastly, I doubt a conventional war is about to break out. I doubt either side is interested in a war of this size. And besides; a world war the Germans didn't start?!
[0] Examples of German diplomacy at its finest: Japan in August 1914, the Zimmermann Telegram and U-boat raids in the Atlantic (during both world wars prior to US entry).
