I never said you must wait until attacked. I said immenant threat (spelling errors notwithstanding).
The President under the constitution was always given the leeway to act when such a threat was present even before an attack occurred. It can't even be rationally argued that Somolia posed a threat to the US nor can it be argued that any nation this century apart from Japan has posed such a threat.
Al-Queda?
Other than a direct attack on American citizens on American soil, the gruesome murder of an American reporter and threats to unleash nuclear and chemical weapons on America, those Al Qaeda guys and their supporters in other countries are really pretty nice people, huh?
