SADDAM HUSSEIN may be suffering withdrawal from the giddy rush of being dictator of Iraq. As his trial resumed last week, he warned the judges of retribution and told them to "go to hell." After witnesses testified about torture under his rule, he said he and his co-defendants were being treated inhumanely by not being allowed to shower, exercise or smoke. "This," Saddam declared, "is terrorism." Finally, he said he wouldn't "come to an unjust court." The next day, he did not show up. But it's not his Iraq anymore: the trial went on.
