Systempunkt
A concept in network warfare, mentioned by John Robb of the Global Guerilla weblog at http://globalguerrillas.typepad.com/globalguerrillas/2006/01/systempunkt_1.html
"When failing a state, the systempunkt is the target which inconveniences the largest number of people through the reduction of critical services. When coercing a foreign state, the systempunkt is the target which has the greatest impact on that state's connections to global markets. In some cases, they are one in the same."
