If you want to secure the entire Strait, sure. My understanding is you'd only seek to hold the area around the Musandam Peninsula, along with a couple of the islands near it.
The entire gulf is at risk. Iran can interdict and cause problems from almost anywhere.
Granted it may not have to be 'the whole thing' but something like it.
