Ethan Melzer, a former US Army soldier, was sentenced to 45 years in prison on Friday for his role in a plot to attack a US military base in Turkey and kill his fellow service members. He had provided sensitive details to a neo-Nazi, pro-jihadist group known as the Order of the Nine Angles (O9A) in connection with its plot to spark a jihadist terror attack. His motivation was to cause a mass casualty event and further the goals of white supremacy and the downfall of Western civilization. The sentence is the maximum penalty for his crimes.
