The other thing to note is that a theocratic police state - Iran - can’t control its drug problem.
How many drugs are imported into Iran via illegal border crossings versus the US? Last time I checked Iran has its border sealed up like Fort Knox. How many SA cartels operate in Iran? I’m going to guess its zero. How many of its own people does Iran murder versus drug gangs murdering iran’s citizens? I’m pretty sure Iran kills way more of its own people. I don’t think it’s a good comparison.
