Yes, the war -is- over.
This is merely an animated re-enactment of it. Not a patriotic piece of patriotishm, as you put it. Apparently you have a skewed perspective of what the majority of Americans think about Germans. The only reason that Nazis is most video games and such are referred to as Germans is because the vast majority of them were German.
I, personally, have no problem with Germany or Germans. I'd be one hell of an idiot if I did, seeing as how I'm about 60% German in origin (and damn proud of it). As you apparently know, being German has nothing to do with being a Nazi.
Now, regarding our president. He is not Hitler, nor could he ever in his wildest dreams become like Hitler. For all his follies, Hitler was an intelligent man. Our president is not.
Now, on to the movie. It was good. I liked it, but it could've been a tad longer, perhaps. Having the German voice acting in there would've been cool, too. Love the original animation style. All in all, good job.
