Black, Bush only has about 6-7 more months in office, he really would need more time to prepare a military attack on Iran or even an invasion. those things take time and we don't have either for Bush to do so on Iran. Plus to make an attack on Iran you need to make sure that your bombers know where they think the program is or the facilities are. Reports are that the facilities the Iranians are using are deep underground and spread far across the country so it takes time to find them all and their is no big reward of succeeding. Seymour Hersh is a good reporter but he needs to stop being a conspiracy theorist and thinking he has the inside information all the time.
