Gee, is *everyone* avoiding the Spain question because we've all seen a documentary on the History Channel on the subject and that's about it? ;D
Saddam is no Hitler. Hitler had a huge dose of charisma and mesmerizing speaking skills, and much, much bigger ambitions. Saddam may WANT to be Hitler (only he knows for sure), but he just doesn't have the skill set. Nor does he have war-hardened, patriotic and stubborn German people, who almost managed to take Europe. Nor does Iraq have anyone with resources that is likely to become an ally.
There is one big similarilty, though -- no one cares about the Kurds unless it's politically expedient, just as no one cared about the Jews for a long, long time. However, the Kurds have decades of insurrection and violence behind them, and as far as I know the Jews were peaceful, except for a few Jewish terrorists running around Palestine trying to create Israel.
