Each of us in the imperial core chooses to live and work every day. We directly contribute to this genocide with our labor and tax money and consumption. We have the power to stop this, we are not powerless. We are all complicit.
Bushnell, acting alone, got a member of the State Department to publicly resign. An ordinary person without wealth and power had a concrete influence on the US government, all alone and with nothing but the willingness to die for what they believed in.
I think Bushnell killed the wrong person, but I can recognize they are my moral superior. I can barely hope to be half as important.
What would I do if my country was committing genocide?
