In grade school we were taught that American foreign policy was about protecting America, and I believed it. As an adult I was able to look into it and I discovered that was false.

Nonstop propaganda is very effective at making people think something, even if they never did the research.
But recently, the President of the United States backed up my conclusion on national television. Washington predicted this. Eisenhower predicted this. And Trump admits it. We've fought wars for nothing more than material wealth. He says at 1:48:53:
"Excuse me. We are energy independent for the first time. We don't need all of these countries that we had to fight war over because we needed their energy. We are energy independent."
