Of course not. To believe that you'd have to be complete braindead f**king moron like Ralph Nader (who claims that)
Really Doubt that. I admit that Gore may not have invaded Iraq but let's forgot that Clinton's relationship with Iraq was hardly Cordial.. The Sanctions, The continous bombing, enforcement of the no-fly zone and Operation Desert Fox. I've no doubt if Gore became President he would use 9\11 as leverage against 'hostile' islamic regimes. But I doubt he would have gone all the way like Bush did.
Iraq was not an Islamic regime, and Gore was critical of the invasion since before it began. He was opposed since day one. Sure Clinton wasn't friendly with Saddam, but who would be? There's no indication Gore would've actually invaded Iraq.
