A new poll shows that a majority of Americans don't believe President Bush's assurances that his planned Iraq war escalation will only be temporary. The new Rasmussen poll asks: "How likely is it that most U.S. troops will be out of Iraq within a year?" The answers: only 17% thought it somewhat or very likely, while 52% said it was "not very likely" and 28% said "not at all likely." That's a total of 80 percent who think it's unlikely — can Americans' hope for progress in Iraq get any bleaker?
