That's how President Bush dismissed reports in the New Yorker that the White House was considering using nuclear weapons in Iran. But that wasn't what he was saying today. In a press conference in Washington, Bush was asked explicitly whether the "options" for Iran "include the possibility of a nuclear strike", Bush replied chillingly
All options are on the table.
Now, that's not saying "we're going to nuke Iran", but its very definitely not ruling it out either, and the only way it can be construed is as an implied threat of first use.
So much for "speculation".
