Who's the biggest embarrassment for the world: Ahmadinejad, Chavez or W. ?

Ahmadinejad, all the way. Chavez can over react a little. W can be just plain thoughtless, redundant, and a little ignorant. Ahmadinejad on the other hand is stupid and inflammatory. Not a good combo.

Personally, I would have to say Chavez. Though, my opinion is biased. My family is living in Venezuela right now, and to tell the truth, I'm more than a little afraid for them. He claims to be a President, yet he is suppressing anyone and everyone that opposes him. Freedom of Speech has almost been obliterated: television or radio shows that speak out against him are illegal. In some parts of the country, you can't get a job unless you say you support him. THe only reason people support him are that most of the people that don't have either left the country, were killed in the riots, or are too afraid to say anything. Venezuela's always been a poorer country, but I've seen more poverty now, while he has been in term, then before.

On the other hand, Bush is a disgrace, also. (I assume you meant him when you say "W.") He has no clear, good reason for sending troops to Iraq, his response to Katrina wasn't the speediest, things just haven't turned out that well for him.

And, sorry, I don't know that much about Ahmadinejad, so I can't say much there.

Perhaps I'm biased because I know the most about him, but W took a great nation and turned its allies against it, all the while profiting from a war that he created using evidence that never existed, killing thousands needlessly. Chavez is a bit paranoid, but who wouldn't be in any country with oil after W? Ahmadinejad? Only time will tell what sort of damage he will actually do, but he's certainly heading towards hell in the proverbial handbasket, and hasn't been an exemplary human being up 'til now.

Ahmadinejad... He is to the 21st century what Sadaam was to the 90s... what Qaddafi was to the 80s. He should study history a little more: If you irritate the U.S., you lose.
