It's actually more because the Rhine is THE iconic German river, like the Volga is for the Russians or Mississippi is for the US... When someone says "German river" the first thing that comes to mind is the Rhine. So in that vein pissing in the Rhine is pissing on Germany.
Of the Thames River for Britain, Nile for Egypt, St. Lawrence for Canada, Po River for Italy, or Yellow River for China
I didn't know there were so many national rivers
I doubt the Dutch down river are very happy about that.![]()
