Iran top leader says Bush acts like someone who is mentally ill

US President George W. Bush and his advisors act like mentally ill people, Iran's Supreme Leader Ayatollah Ali Khamenei said Tuesday. "Look at behavior of the US president and members of his team, their words are like those of the mentally ill," said Khamenei, who has final say on all matters in Iran, on Tuesday at a ceremony honoring the late Ayatollah Ruhollah Khomeini, founder of the Islamic Republic. "Sometimes they threaten, sometimes they order assassinations ... and sometimes they ask for help - it's like mad people staggering to and fro," he said. Khamenei said the erratic behavior of the US leader is rooted in the failures in Afghanistan and Iraq and he urged nations to resist American bullying.
