an early commander of Strategic Air Command. LeMay was a very vocal advocate for a strong national defense, particularly as regards nuclear weapons. Being a Unified Command, another major concern for Gen. Butler was interservice rivalry, having soldiers, sailors, airmen and marines in one command. There had been decades of rivalry between the branches of the U.S. military regarding control of nuclear weapons. Even though a compromise had established the Joint Strategic Target Planning Staff, there were systemic and institutional problems that could not be overcome. USSTRATCOM was re-structured 1 October 2002 by Secretary of Defense Donald Rumsfeld. It was now to merge with the United States Space Command and assume all duties for full-spectrum global strike, operational space support, integrated missile defense, and global Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) and specialized planning. Its duties now include intelligence and cyber support as well as monitoring orbiting satellites and space debris. In February 2008, USSTRATCOM succeeded in destroying a satellite, USA193, about to re-enter the earth's atmosphere. USSTRATCOM also supported United States Africa Command's 2011 military intervention in Libya in a variety of ways, including long-range conventional strikes and intelligence, surveillance and reconnaissance (ISR). An intention by the U.S. Air Force to create a 'cyber command' was announced in October 2006. On 21 May 2010, part of USSTRATCOM's responsibility regarding cyber-warfare operations was spun off into a 10th Unified Command, the United States Cyber Command. As a result, USSTRATCOM's Joint Task Force-Global Network Operations (JTF-GNO) and Joint Functional Component Command – Network Warfare (JFCC-NW) were disestablished.
