Senate Democrats asked President George W Bush on Friday to order a new US intelligence report on Iran to avoid the errors that plagued prewar assessments on Iraq. Five Democrats, headed by Senate Majority Leader Harry Reid of Nevada, wrote to Bush requesting a new National Intelligence Estimate, or NIE, while the United States is involved in an international diplomatic effort to get Iran to curb its nuclear ambitions. The Democrats want an NIE, the intelligence community's most authoritative written judgment, to address several points including Iran's nuclear programme and its military and defence capabilities.
