Counterterrorism strategies are a government's motivation to use the instruments of national power to defeat terrorists, the organizations they maintain, and the networks they contain. If definitions of terrorism are part of a broader insurgency, counterterrorism may employ counterinsurgency measures. The United States Armed Forces uses the term foreign internal defense for programs that support other countries' attempts to suppress insurgency, lawlessness, or subversion, or to reduce the conditions under which threats to national security may develop.

PI2G 2F
The number (; spelled out as "pi") is a mathematical constant that is the ratio of a circle's circumference to its diameter, approximately equal to 3.14159. The number appears in many formulas across mathematics and physics. It is an irrational number, meaning that it cannot be expressed exactly as a ratio of two integers, although fractions such as \tfrac are commonly Approximations of π, used to approximate it. Consequently, its decimal representation never ends, nor repeating decimal, enters a permanently repeating pattern. It is a transcendental number, meaning that it cannot be a solution of an equation (mathematics), equation involving only sums, products, powers, and integers. The transcendence of implies that it is impossible to solve the ancient challenge of squaring the circle with a Compass-and-straightedge construction, compass and straightedge. The decimal digits of appear to be random sequence, randomly distributed, but no proof of this conjecture has been fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
