Did the authorities in Oman ask for help?

Yesterday a ship was hit by an explosive device in the Strait of Hormuz. The reports I read stated it was fired from Oman. I am fairly certain that was not the Oman government carrying out an aggressive act of terror. 

However.

It is up to Oman to investigate and seek out the reason for the explosion and whom carried it out. Oman is a very wealthy country quite able to carry out its own interventions for events gone wrong.

It is not the business of the USA to police every incident in the world. The only way the USA should carry out any missile strike is if an ally requests assistance.
