The Iranian nuclear Watch has been heating up lately on a number of fronts.

1.  U.S. Carrier Battle Groups:  The U.S. Navy has moved two carriers into the Gulf.  You can check U.S. carrier positions here.

2.  Iranian Nuke Scientist Killed:  A James Bond-like magnetic bomb attached to the Peugot of Iranian nuclear scientist Mostafa Ahmadi Roshan killed the nuclear technician near Natanz, Iran's primary nuclear facility area.

3.  Iranian Oil Embargo: The European Union agreed to an oil embargo.

4.  Iran Holding Naval Exercises: More provocations to come.  The U.S. Navy recently rescued some Iranian sailors who were in trouble.  Think they'll remember that.
