There is absolutely no reason why the U.S. should intervene in this.
Whether you like it or not, the United States guarantees freedom to sail in international waters of all American flagged ships (their crews, passengers, cargoes, etc.). Not only ships owned by Americans or American corporation but all ships registered as American, whether not owned by foreigners or foreign companies or not.
By treaty, which both the U.S. and the Marshall Islands agreed to (and enacted into law), the U.S. has to protect all Marshall Island flagged ships just as the do American flagged ships.
This is not an American flagged ship.

No it doesn't. It means we would protect them if invaded. Iran seizing a ship that has no connection to the Marshall Islands whatsoever except on paper in not an invasion. And I certainly don't understand this desire to go to war over the Maersk Freakin' Tigris.
