Always....it was a Bell 212 if I remember the video correctly....which is almost exactly a UH-1N....which the USMC still operates as well.
The Iranians can be a bother....but it will be a short one if it comes to an all out dust up.
There are three Carrier Task groups in the area....not just the one.
Add in the USAF ability to move large numbers of aircraft to the area within just a few days....and the situation changes quickly.
I do not see the Israeli's using their Nukes....as that is a jar no one wishes to open except in self defense and then only in extremis.
