John Michael Cornwall (born 19 August 1934) is an American theoretical physicist who is known for the Pinch Technique. Cornwall invented the Pinch Technique for calculating gauge-invariant off-shell Green's functions for QCD and other Yang-Mills theories, showing how a dynamical gauge-invariant mass arises for QCD gluons and how such gluons lead to confinement and other non-perturbative phenomena. He has also written some 40 papers on space plasmas such as the magnetospheric ring current, leading among other things to a detailed understanding of the dynamical role of electromagnetic cyclotron instabilities in the magnetosphere. Cornwall published with Richard E. Norton in 1973 one of the earliest papers on dynamic symmetry breaking in Yang-Mills theories. He was an advisor to the Institute for Defense Analyses in Alexandria, as well as to the National Aeronautics and Space Administration (NASA). He was a member of the Defense Science Board. He is a long-term member of the JASON Advisory Group. He is a Fellow of the American Physical Society (2005), the American Geophysical Union, and the American Association for the Advancement of Science. The JASON study was informed by 'The Lincoln Labs" study which also posed challenges due to limitation on its use. Missile defense systems are a type of missile defense intended to shield a country against incoming missiles, such as intercontinental ballistic missile (ICBMs) or other ballistic missiles. The United States, Russia, Taiwan, India, France, Israel, Italy, United Kingdom and China have all developed missile defense systems. The term "Missile defense system" broadly means a system that provides any defense against any missile type (conventional or nuclear) by any country. Any mechanism which can detect and then destroy a missile before it can cause any harm is called a missile defense system (MDS). The role of defense against nuclear missiles has been a heated military and political topic for several decades. However, missile defense is no longer limited to interception of strategic nuclear weapons. The gradual development and proliferation of missile technology has blurred the line between the technologies for the interception of tactical missiles (usually short to intermediate range with non-nuclear payloads) and the interception of strategic missiles (usually long ranged with nuclear payloads). High-performance tactical ballistic missiles carrying non-nuclear payloads now have the ability to affect strategic balance in conflict zones. Likewise, high-performance tactical missile defense systems can now influence force deployment strategies. Defending against an attack by a cruise missile is similar to tackling low-flying manned aircraft and hence most methods of aircraft defence can be used for a cruise missile defense system.
