It's been proven that Abu Nidal was living on the Iraqi dole in Baghdad. Remember him? Pushed American Leon Klinghoffer of the Aquili Lauro cruise ship way back when; as well as having been implicated in many other international acts of terrorism before he retired to his resort on the Euphrates.
Then there's this butcher, Zarqawi, bin Laden's deputy who, apparently, had been organizing (with the knowledge and assistance of Iraqi Ba'athists) this current "insurgency" you see going on in Iraq since the end of the actual war with Iraqi troops.
And there are others.
Paying stipends to families of "Palestinian" terrorists...which Saddam Hussein is on videotape confessing to with pride.
Those things have been proven...way back when. You say you haven't been paying attention because of personal priorities, that's fine. But, why come in here and ask the forum to do your research for you?
Google "Hussein and terrorism" or "Saddam Hussein's ties to global terrorism" or something like that. You'll find articles on the matter.
