School of the Americas: True or Fake?

The School of the Americas, or more formally known as the Western Hemisphere Institute for Security Cooperation, is supposedly located in Fort Bennings, Georgia for 59 years although the government neither denies nor confirms its existence. This "School" trains people, mostly Latin Americans, in counterinsurgency techniques, sniper training, commando and psychological warfare, military intelligence and interrogation tactics. These graduates have consistently used their skills to wage a war against their own people to preform coups and the overthrow of their government. I believe that this is a harmful and reckless idea whether it exists or not, America does not need constant involvement in every country and certainly should not contribute to the overthrow of governments where we could possibly make things even worse. America has its own problems to deal with and no matter how hard we try you can never replicate our democratic government anywhere else. I know this sounds selfish, but if we minded to our own problems our country would have less political and economic turmoil, therefore we could help these countries in a more efficient way. We need to tend to ourselves before tending to other countries, or else everything will be more chaotic and there will be no hope for a government that's not corrupt.
