Iran is stirring up violence in Iraq. Iran is stirring up violence in Lebanon. Iran is stirring up violence in Gaza. Iran is pushing Syria towards confrontation. Hundreds of US servicemen have been killed by more and more sophisticated Iranian weapons. The downing of a growing number of US helicopters is another sign. A third US strike carrier force will be dispatched soon to the region. The US forces will have to react to Iranian hostility, that shows up daily with Iranian provocations in the Gulf. If an embargo will lead to hostilities, this will lead to the destruction of the Iranian missile systems and to the destruction of their Navy. Their Air Force will come down by itself despite delivery of spare parts by Germany. The nuclear sites will not be attacked. This will only happen if the top brass of Iran will still be defiant. It is to be hoped, that the nuclear sites can be dismantled peacefully.
