While the interceptor did destroy the mock ICBM, Philip E. Coyle, a senior fellow at the Center for Arms Control and Non-Proliferation, told CNN that only “two out of the last five attempts” have been successful and “that is only a 40 percent success rate since early 2010. In school, 40 percent isn’t a passing grade. Based on its testing record, we cannot rely upon this missile defense program to protect the United States from a North Korean long-range missile.”
