False.
First, "the Kurds" were not a single entity, there were actually 3 separate Kurdish orgs resisting Saddam. Are you speaking of the PUK, the KDP, or the IMK?
The opposition hardly stopped there. Pretty much ALL of the Shi'a south hated Saddam, which is why they revolted. You have Arab minorities based in Baghdad that wanted Saddam dead by any means. You have Iraqi Army defectors scattered about helping where they could. The al Dawa folks and a few other anti-Saddam groups that were based out of Iran and the UK had plenty of contacts and resources within Iraq during Saddam's rule, that's how we got a lot of our intel from in the days and hours before the 2003 invasion.
And let's not forget those wacky Heshemite Iraqi monarchists who ran the show prior to 58. They've been in the back ground for awhile now and have always wanted to turn Iraq into a constitutional monarchy.
So let's dispense with the notion that Saddam was untouchable due to no real opposition being present. Saddam didn't have super elaborate personal security and impersonators just because some Kurds up north hated him.
"Betrayed" is I suppose a good word to describe it. Certainly quicker to type than "incited them to revolt with the promise of support then left them to face overwhelming numbers and firepower alone."
