The Dreyfus Affair was over 100 years ago, in France. The french were kind of antisemitic then. But that was a long time ago. Back then the USA conquered the Philippines and crushed the democracy movement there, we installed a fake democracy and ran the place ourselves because we thought we needed military bases. Things have changed a whole lot since then, when is the last time the USA has done that? Back then we had oil barons pretty much running the country and getting richer off the rest of us. We don't like it when spies give our technological secrets to other nations. Pre-1900 did we really have any important technological secrets? And here you are talking about Dreyfus, a Frenchman persecuted by other Frenchmen over 100 years ago. It sounds like you don't have any good recent examples from the USA.
