If you want some valid links then here,
http://news.bbc.co.uk/2/hi/middle_east/3483089.stm . That is a credible news source, non-us.
"Attacks are now a daily occurrence in Iraq. Whether or not Zarqawi is behind them all, he is seen by the US as the biggest obstacle to their hopes of progress in Iraq - their most dangerous enemy in the country."
It basically says, that he is not responsible for the small daily attacks. But he IS resposible for the major attacks and assinations that have been going on.

So I suppose those were imaginary myth terrorists they captured?

I searched this "myth" on google. Not supprisingly, the only article that I could find find about this was 1 single aljazeeraha OPINION piece.

Opinion is not fact, and his opinion is strictly his and does not reflect the rest of the worlds views on Zarqawi. I think its fair to say that he's been 'hyped' up by the media and given more credit than he's actually done. Thats fair to say. But like I said before, he is very real and a very dangerous man. If you think otherwise then you should read those links and search him on the web. Its not just the US government that's after him, that should tell you something about the serious nature of the man.
Here are more current links from your own source on zarqawi. I find that interesting that your own source would have more articles on his reality than his myth. That should tell you something.

Those are more articles from the same news source you provided.

The guy who claims he is a myth is somewhat credible, he was a senior us weapons inspector in iraq, but you have to question his motives. Why is it that there was no follow up stories on his statements? No where could I find more articles on zarquwi as a 'myth' other than that of Ritter. It leaves much to be questioned on the validy of his comments. Notice that I showed you multiple sources that support my view, and could only provide one, namely Ritter's against my view. Therefore, how can one sensibly conclude that Ritter is right and everyone else is wrong, if I am to cross reference as you suggest?
If you can find more sources on this 'myth' that have official backing to it, I would be interested in reading them. I could only find sources based off of Ritters one opinon paper, but nothing based on other independent high government official sources. (US or foreign)
