While at port in Guam a team of highly trained terrorist from Iran backed by wealthy extremist from around the middle east manage to get a team of over 200 to take the submarine while a force of 100 gun down defenders.
Once leaving port they fired a nuclear torpedo at a fleet of ships including an air craft carrier sent to destroy them.
Would the Russian's be blamed? Would the US invade Iran?
If the Missile Submarine managed to survive would the US work with Russia to bring it down or is working with the Russian's off the table?
This scenario makes no sense for several reasons:
1. Imperial Iran was a strong ally of the United States in 1967 and would have no reason to attack it.
2. Iran is Shia and Persian, while most of the Middle East is Sunni and Arab. They usually don't work together.
3. Guam is a major base for the United States Pacific Command and almost half of the island is owned by the military. The terrorists would have to fight through all of that.
4. How are hundreds of terrorists going to get to Guam with their equipment? Even though airport security screenings didn't start until 1972, it's quite unlikely that hundreds of armed men, presumably Persian and/or Arab, are going to be able to fly to Guam and be there at once and bring along enough rifles, ammunition, and explosives to take out a naval garrison without arousing suspicion.
5. How are the pirates going to know how to operate a submarine? To my knowledge the former
USS Trout (
Tang class) was Iran's first submarine, and Iran didn't acquire it until 1978.
6. Presumably this is a missile submarine too. I'm not sure why it would be docked at Guam since that would make its location known, and the United States Navy prefers to keep its ballistic missile submarines out at sea to avoid detection. If a ballistic missile submarine did go to Guam it would probably be due to some unplanned contingency, so the hundreds of terrorists would have to be waiting around for something like that to happen or otherwise arrange for something to happen to the submarine and then hope that it would divert to Guam instead of more developed ports in Occupied Japan, Hawaii, or the United States West Coast.
7. If it's a missile submarine it's quite likely to be nuclear powered as well. Nuclear energy was still a rather new technology in 1967, and Naval Reactors was and still to this day is extremely secretive about all details of the nuclear propulsion system, so how would the terrorists know how to operate it?
8. The only nuclear torpedo deployed by the United States Navy was the
Mark 45, and its limited range and wire guidance system makes it seem unlikely that it would have been deployed on a ballistic missile submarine.
