Putin's declaration yesterday that "those who try to blackmail us with nuclear weapons should know that the weathervane can turn and point towards them," the threat of a nuclear catastrophe looms again. Here in Portland, Oregon, we live downstream from the Hanford Nuclear site. Next year, the Vit Plant, which is designed to turn plutonium waste into glass to keep it inert, is scheduled to go online. The only problem is it has a black box design that critics believe could lead to disaster. How have we come to this point? Host Jacqueline Keeler will examine how the colonial origin story brought us here.
