From The Guardian:It is now evident that the US is planning some kind of military strike against known, and suspected nuclear sites in Iran, with some kind of covert operation to overthrow President Mahmoud Ahmadinejad. It is a high-risk option, as the US military have made plain to their president, and they're not keen to do it too soon. "But Bush cannot allow Iran to go nuclear on his watch. And the chances of diplomacy succeeding in this are nil," the respected military historian and New York Times correspondent Michael R Gordon said in London this week.
