War With Iran?

Today we learn that a former FBI agent has now gone missing in Iran. And now, a few questions naturally arise, such as:

1. What was this man doing there? The State Department claims that he was on private business in Iran, but was he really?
2. DId the Iranians capture him, too?
3. What are the Iranians up to?
4. What is the American government up to?
5. Two carrier battle groups were recently deployed to the Persian Gulf, and there have already been skirmishes between US/Coalition forces and Iranian assets in Iraq. Additionally, there are rumors that there are US intelligence operatives already in Iran, laying the groundwork for military operations, and that the US intends to strike next month on Good Friday. Add to that the fact of reports that President Ahmadinejad of Iran hopes to usher in the coming of the Mahdi, the Twelfth Imam. Could we be heading for an all-out war with Iran?
6. If we’re heading for war, what will the streets of Paris, London, Berlin and Rome look like?
7. If war erupts, what will the Russians and Chinese—both on cordial terms with Iran—do?
