"On April 12, Antal resigned his commission as an officer in the Army because of his conscientious objection to the United States' drone policy. In a letter addressed to Commander-in-Chief Barack Obama, Antal wrote, "The executive branch continues to claim the right to kill anyone, anywhere on Earth, at any time, for secret reasons, based on secret evidence, in a secret process, undertaken by unidentified officials. I refuse to support this policy of unaccountable killing." In doing so, he joined other previous members of the armed forces who have addressed Obama to criticize his drone strike policy, including four former members of the Air Force who penned a letter in November of 2015 warning the president that the strikes "served as a recruitment tool similar to Guantanamo Bay."
The White House has defended the use of force in certain situations. "Since his first day in office, President Obama has been clear that the United States will use all available tools of national power to protect the American people from the terrorist threat posed by al-Qa'ida and its associated forces," reads a 2013 fact sheet on policies and procedures for counter-terrorism operations outside the U.S. and areas of active hostilities.
Earlier this year, the Obama administration agreed to publish a redacted version of the so-called playbook for U.S. drone operations overseas. Antal hopes that with the publication, Americans will open their eyes to what is really happening with armed drones. The administration has not made clear when the documents will be released."
