I’ve read here with some alarm, that Iran is capable of placing missile launchers inside shipping cargo containers and firing them at see from these disguised locations. I wonder if we are able to remotely track the radiation from a future Iranian nuclear warhead on such a missile at sea? A mighty unpleasant surprise to have one launched at us from a concealed decoy commercial cargo ship and hit us with almost no warning.
A nuclear armed Iran poses an existential threat to everyone, just based on their public official statements and rhetoric. I tend to believe they mean the stuff they have said.
