Actually, we have real info on Iran and terrorism against the US; there was a lot of testimony about it recently in the legal cases where survivors of terrorism, either people who were attacked or kidnapped but didn't die or people whose relatived did die in such an attack or kidnapping, are suing the sponsors of terrorism thanks to recent legislation allowing such suits. Look up the cases, try Scicippio (sp?) or that hostage guy whose name escapes me. Most of them are v. the Government of Iran. And since several adminstrations by now have tried to STOP such suits, even Clinton, the cases had to be made very well. You can also look for the Damerell et al case, which is ongoing now but hasn't been decided yet (well, the culpability of Iran has been proven; whether the litigants get anything is what hasn't been decided yet).
