The military–industrial complex describes the relationship between a nation’s military and the defense industry that supplies it, seen together as a vested interest which influences public policy.

President Eisenhower’s farewell speech to the nation the retiring president warned of the dangers of allowing a Military-Industrial Complex to take control of the United States. The Military-Industrial Complex is a term that denotes a symbiotic relationship between a nation’s military, economy, and politics.
The U.S. sent to Afghanistan nearly 600,000 small arms, 76,000 vehicles and 208 airplanes to Afghanistan’s military and police from 2003 to 2016, according to a 2017 Government Accountability Office report, one of the few such compilations. The U.S.-led military coalition documented deliveries of 174 Humvees, nearly three million rounds of ammunition, and nearly 100,000 2.75-inch rockets during the period, night-vision goggles and even small drones for intelligence gathering.
The Department of Defense has a handful of arms manufacturers. You may recognize some or the names: Colt, Daniel Defense, Remington Arms Company, and FN America. FN is also working to help develop new guns featuring revolutionary technology. Lockheed Martin Corp. is the largest arms manufacturer in the world. Boeing, Northrup Grumman, and Raytheon rely on the U.S. military for anywhere from 44% of their revenue (Boeing) to 89% of their revenue (Lockeheed).
“FN America was recently down-selected and contracted to produce two prototypes for the U.S. Army’s Next Generation Squad Automatic Rifle program,” says Greg Livermore, FN’s vice president for product management.

All of those arms manufacturers are now trying to negotiate a situation that will result in fewer arms sales. Don’t you know they will be promoting another war? They don’t care where it is and how many lives are lost or how many injuries are sustained?
It was WWII followed by the Cold War that created jobs for Americans in those arms manufacturing companies. Many have said that wars are what keeps America out of depressions.
Are they correct?
