Brad Allenby, a professor in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools, whose expertise includes geopolitics, the implications of emerging military technologies and military ethics, has cast doubt on the legality of any punishment of Arizona’s Democratic Senator Mark Kelly, a U.S. Navy veteran, for his statements about the rights of members of the military to refuse to obey illegal orders. On social media, President Donald Trump has accused Kelly of seditious behavior and said the federal government might recall Kelly to active duty so he could be tried in a military court. The debate over this issue was also explored in an earlier Arizona Republic article in which Allenby is also quoted.
