Why is it the US? I think it is the people doing the drugs that could be partially to blame, not the US. I think the US makes it pretty clear it does not support drug use by throwing thousands in jail yearly that take drugs.
The murders in Mexico are committed by the drug cartels. Approximately 90% of the drug cartel’s profits come from sales to US dealers, who then sell the drugs to the end users. The drug cartels only exist because drugs are illegal in the United States, and most of their profits come from marijuana, because most people in this country are not stupid enough to do things like heroin. If they were not criminalized, we would probably have more addicts, but we would not have the gang violence, and Mexico would not have its thousands of murders per year (hundreds of which have been of innocent victims with no connection to drugs). This is a bipartisan problem.
