The Iranians have missile technology which allows them to fire a missile with pinpoint accuracy. They know that the US knows it.
They are attempting to start an International incident. This will deflect the world's attention from their nuclear bomb making program.
They know the US knows what they are attempting.
If there is one round fired from one of Iran's rubber dinghies which hits a US warship WW111 will have officially started.
WWII would not begin because three warships shot down a missile and sank some rubber dingies and or fast boats. BTW, there are no missile types that can be carried on those small boats with the capability to sink an aircraft carrier like the Truman or the accompanying vessels. Those little boats were being targeted by a wide assortment of weapons before they even got close.
