Osama does not want us to attack Iran. That's why he makes it look like He is goading us into attacking Iran.

You might have a point were it not for those pesky documemts of Zarqawi's (graciously provided by Guest,Woody), that Osama had no reason to anticipate would be captured by US forces. If those documents are real and not invented by the US government, they provide us with all the evidence we need that al Qaeda wants the US to attack Iran.
