Personally not been an American, I shouldn't really comment, But backing saddam to invade and in the process destroy the most western influenced city in Iran, after the Shah was toppled from power by the theocracy, the bungled rescue attempt of American hostages and subsequent parts for oil debacle with Iran, Along with his hypocritic remarks about America not dealing with terrorists whilst actually doing so, although in light of Bush I would not say he was a bad president but mediocre at best.
But like I say ,what would I know not having lived in the states during his administration.
Just an outsiders perspective.
Reagans economic model wasn't so bad it did cut a lot of red tape and did a lot to create job growth, its just unfortunate that people started to regard it as a kind of gospel and didn't actually pause to examine other models and causes and effects of policy, deregulation = good,
no regulation = bad!
