Is the UK gearing up for Iran war?

After reading this article here I'm starting to wonder if the new Brown government is gearing up for a war with Iran, as the past foreign secretary Jack Straw ruled out the option of military action as at least he knew that Iran is not Iraq and any invasion or even just a 'limited bombing campaign' would cause more resentment and threat of terror attacks and just the plain fact that Iran has a much more larger and well equipped army than Iraq did. With an over stretched army bogged down in Iraq and Afghanistan there is no logic in attacking a third country. However politicians are far from being logical thinkers.
