MIDDLE EAST - As tensions between Iran and the West over Tehran's threats to block a crucial oil supply route increase, there is much speculation whether the situation will evolve into a full-scale military conflict.

IRAN - A senior Iranian Revolutionary Guards commander said on Thursday the United States was not in a position to tell Tehran "what to do in the Strait of Hormuz," state television reported, after the US said it would preserve oil shipments in the Gulf.

USA - If our founding fathers could see the cesspool that the US Congress has become today, they would roll over in their graves. Most Americans don't realize this, but we already have a "part-time Congress". Members of Congress only "work" a little over a third of the days on the calendar. The rest of the time they have off. It is no wonder why so many members of Congress are involved in so much corruption - they have so much free time on their hands that they are bound to get into trouble.
