Are you not aware how metonymy works? Of course there are nice Americans. There are nice people everywhere. “The Americans” here is being used as a stand in for the actions of their government for at least the last sixty years. Longer, if you include the centuries of land theft, genocide, slaving, pillage, and terror. All of these acts were sanctioned by a government that was elected, supported, and funded by American citizens. This is who they are. The presence of a few friendly faces in a sea of greedy, rapacious cunts doesn’t change much.
