From an Associated Press article published today:
"The United States was the first to say that Iran was a threat in this way, to try and convince the international community that Iran was trying, under the cover of a civilian nuclear program, to actually bring about a nuclear weapons program," Rice said on CNN's "Late Edition."
Perhaps the situation is slightly different, but this sounds a lot like what was being said about Iraq right before U.S. troops and the "coalition of the willing" went over there.
