As millions of Americans are about to go hungry due to the US government refusing to fund SNAP, just remember that only two countries voted against making food a basic human right. The US and the terrorist colony of Israel
They went after Germany because Germany declared war on them when they went to war to war with Japan. There's nothing ironic about fascists getting into fights with fascists only to then... Still be fascist years later.
If the US weren't already fascist and went to fight the Nazis out of some sort of moral duty only to later wind up becoming Nazis themselves then yes that would be ironic.
