Hitler was able to consolidate a massive amount of political power in Nazi Germany and had the military capabilities to challegne the world powers at the time. Plus, he had a cult of personality and a propaganda machine that silenced all opposition and built up a fever-pitched nationalism.
Ahmadinejad has absolutely no power whatsoever. He’s a brainless party hack that Khamenei stuck into the presidential seat after Khatami opened some cracks in Iran’s authoritarian armor. Iran can only boast and talk big because, like North Korea, they can never reach military parity with the likes of the United States or even China. Add to that Iran’s terrible economy, repressed and hostile middle class and youth and their inability to become a major powerbroker in their own neck of the woods (the Middle East) and I don’t think we even have a close match to Hitler.
Ahmadinejad is an awful, evil dude, but the Hitler comparison just doesn’t fly.
They are effective at it too in that part of the world, irrespective of what we perceive as his lack of capability. You see, it is really not about what we think (except in so far as he can continue to get moonbats to run intertference for him here), it is about what the people over in that part of the world think about what he did here yesterday and today.
And, if they obtain nuclear weapons, then they will have the military capability, and the fanatical will, to cause death and destruction on the same scale in a much shoirter time frame.
For those reasons, and because there are so many who want to "dialogue" with the madman, the comparison to Hitler and the danger he posed do indeed fly.
