Brent Scowcroft Center Deputy Director Magnus Nordenman writes for Defense One on why competition between established and emerging powers will be expressed at sea in the 21st century:

The US decision to escort US-flagged ships through the Strait of Hormuz after Iranian patrol boats fired warning shots towards the merchant vessel Maersk Tigris and forced it into an Iranian port says much about the changing global maritime domain, and how it is increasingly competitive and contested by emerging and revanchist powers.

This is hardly just an American headache. Earlier this week, Iranian patrol boats also fired at a Singapore-flagged cargo vessel transiting the Gulf, which further raised tensions.
