Maj. Gen. Michael Fortney, the vice commander of Air Force Global Strike Command, speaks about nuclear deterrence during a Striker Speaking Series symposium at Ellsworth Air Force Base, S.D., July 21, 2016. Fortney was one of four panel members at the event and spoke on four assertions, or myths, that many in the general public believe about nuclear arsenals and how Airmen can overcome misperception with knowledge.
