America is a functioning democracy so individual Americans are much more responsible than individual Russians for the bullshit their respective countries do.
> America is not a democracy in a strict sense, its a republic
Most republics are democracies. You seem to think "democracy" is equivalent to "direct democracy," but a direct democracy is only one type of democracy. A republic is another form of democracy.
America is certainly a democracy (for now; who knows what will happen in two years)
But did America ever pay reparations for centuries of enslaving its own people? Where is the accountability?
