TEHRAN - After the U.S. failed to form an international coalition in the Persian Gulf, Iranian, Russian and Chinese armies launched a joint naval maneuver, codenamed "Naval Security Belt", in the northern part of the Indian Ocean and the Sea of Oman. The drill started on December 27 and lasted for four days.

 Many media outlets interpreted the maneuver as a "clear warning to America". Some main political and geopolitical aspects of the wargame are given here:

Iran's dominant position in the region cannot be overlooked

The most significant aspect of the maneuver is Tehran's clear message to those countries that seek to isolate Iran through economic and political pressure. Through holding this joint maneuver, Tehran sent this warning to the foes that Islamic Republic is a power that world powers such as Russia and China cannot close their eyes to.
The Turkish Anatolia news agency, quoting experts, said, "The maneuver is a clear message from Tehran to Washington." The state-run news agency also said the maneuver was conducted at a time that Iran is decreasing its commitments to the 2015 nuclear deal, officially called the Joint Comprehensive Plan of Action (JCPOA). 

In its editorial, the Al-Rai Elium newspaper also said "An Iran which is facing the harsh U.S. blockade will profit furthermost from this maneuver since it will shatter the U.S. blockade, at least psychologically, and shows that Iran is not an isolated country and has strategic friends at the international level."
The widespread coverage of the joint exercise by regional and overseas media indicated that Tehran has selected a suitable time and good thing to indirectly show its power to the United States.
