Iran offered the US a package of concessions in 2003, but it was rejected, a senior former US official has told the BBC’s Newsnight programme.
Tehran proposed ending support for Lebanese and Palestinian militant groups and helping to stabilise Iraq following the US-led invasion.
Offers, including making its nuclear programme more transparent, were conditional on the US ending hostility.
But Vice-President Dick Cheney’s office rejected the plan, the official said.
One of the then Secretary of State Colin Powell’s top aides told the BBC the state department was keen on the plan – but was over-ruled.
“We thought it was a very propitious moment to do that,” Lawrence Wilkerson told Newsnight.
“But as soon as it got to the White House, and as soon as it got to the Vice-President’s office, the old mantra of ‘We don’t talk to evil’… reasserted itself.”
