Here we go again. As the U.N. nuclear watchdog lands in Iran for another round of nuclear talks Monday, Tehran says that it will hold military drills in the southern part of the nation to prepare for attacks against nuclear centers. The U.N. team will spend two days to make sure that Iran is not secretly making nuclear weapons. The military exercises come as speculation increases that Israel may strike the nuclear facilities. The U.S., however, reportedly believes that an air strike by Israel will be a huge task, requiring at least 100 jets. In response to mounting sanctions from the U.S. and EU, Iran cut off oil sales to all British and French companies on Sunday.
