Has Iran now guaranteed that they will be attacked? According to this article, Iran "has stopped conducting oil transactions in U.S. dollars." Iraq did the same thing in 2000, and they were attacked based on false pretexts a couple of years later.
What false pretext(s) will the U.S. use to bomb Iran? They are already being severely demonized by the U.S., minor events are being overblown (or perhaps fabricated), and Bush, Cheney, and their ilk constantly refer to the supposed Iranian "threat."
Sounds like all the propaganda we heard about Iraq prior to its invasion, doesn't it? Take everything you hear about Iran with a grain (or handful) of salt.
