"Whereas it is widely recognized that the US-led war in Afghanistan is illegal under international law, because it was never authorized by the UN Security Council, most Americans have believed that it was morally justified as a response to the 9/11 attacks, and many believe it is still justified as a necessary means to prevent another attack originating from that region. My lecture will present evidence showing that both of these beliefs are untrue, so that the 9/11 Truth Movement and more traditional Peace and Anti-War groups should be able to combine forces to oppose this illegal and immoral war."
