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

Have to stop you right there. The “war on drugs” absolutely has created the conditions for the drug trade and the murders. If you criminalize a large part of the economy, then only criminals will profit from it. If we had sane drug policy, there would not be the profit that attracts these criminals. Additionally, the US intelligence services (and other nations) have a long documented role in cultivating the drug trade for diverse reasons: for profit and paying for operations, for control of regions, and to provide a reservoir of violence to disguise or facilitate their work.
