> The war on drugs definitely didn't cause the drug trade or the murders

You should be a lot less confident in your opinions. The war on drugs required violent interventions against drug production in Mexico, which directly created militarized, violent drug cartels.

Example: pressured by the US, Felipe Calderón launched Operation Michoacán in 2006 with U.S. backing and funding. He deployed tens of thousands of federal forces. Mexico has recorded more than 463,000 homicides since that declaration of war on the cartels, a huge increase.

Just look at the data.

> and he said "mostly our fault". If it takes 3 seconds to think of things we didn't cause

He said "mostly" because he knows there are counterexamples, so providing counterexamples doesn't contradict his point.

> Mostly the US has a hand in stopping communist governments where the citizens are kept as slaves.

This is such a genuinely undiscriminating statement that I can't help but categorize it as dumb. I don't usually say this, but you need to stop listening to propaganda and pick up a few actual history books. Until you do, any discussion is pointless, because you're so stuck in your ideology that facts can't penetrate the bubble.

That's really all I have for you. It's up to you to fix yourself.
