Many media sources are claiming that Bush & Cheney are close (with lots of help from Israel) to launching a "Pre-emptive" attack on Iran.

Just how does this prospect of an explosive Iran invasion or war,launched by the lame duck Bush Administration go down with the 3 front running presidential candadates i.e. Obamma,Hilliary and McCain?
If there is any good (and maybe even vital) question the US media should be asking the candidates,hypothetically or not,its this one!
