In USA Today's world, saying its a "last resort" is evidence of a war-mongering madman. Saying "all options are on the table" is evidence of maturity.
USA Today's editorialist goes on to make the claim that the US with nukes is more dangerous than Iran with nukes. In essence, Duncan Hunter is scarier than Ahmadinejad. What he means, though, is that a Europe that has no intentions of stopping Iran's nuclear program is terrified that the US might do it, and so are the writers at USA Today.
Of course, in my view if Ahmadinejad thinks Hunter is scarier than he is, that might actually be a good thing, I think.
Go Hunter.
