The problem is that fear-based problem solving often just becomes problem avoidance. People become afraid to say there's a problem so it _looks_ as if the problem is solved, but the problem just becomes more buried and actually gets worse.
So, it might help Americans _think_ that the drug problem is solved, but not actually help us solve the drug problem. And I suppose when we push punishment, we're mostly pushing problem avoidance, and so it helps people Americans avoid problems more, so I guess it'd be successful in that.
That’s a way of viewing it, but of course it assumes logical planning by reasonably bright individuals. So it’s begging the question somewhat.
And a nice distraction from the Epstein files.
I think even Bush would recognise it didn't really work out that way with Iraq, but hey, maybe this administration has unlocked the secret.
