Do they? I just looked at a map and I see very little oil infrastructure on that side of Hormuz plus isn't Oman Iran aligned?
It also looks fairly easy to mine/blockade outside of their territorial waters. You don’t need that many drones to make the whole area unusable for marine transport. The strait is the clearest choke point but I don’t know how much bypassing it would help UAE
Fujairah, on the other side of Hormuz is the fourth largest bunkering hub in the world. That’s not “little oil infrastructure”
They do, it's only like 1-2 million barrels a day in capacity right now.
You should visit Fujairah ! Huge facilities there.
No expert but I always got the impression Oman was a neutral party. They help run the Hormuz with Iran but largely neutral in world politics.
