Iran is continuing with its habit of provoking the United States. Recently, Iranian vessels approached a US Navy ship in international waters causing the US to fire warning shots.
Iran is testing the United States and the resolve of its President.
Trump and numerous officials in his administration have spoken again Iran and its provocations and aggression and have vowed to ensure this changes. The US has declared itself committed to making sure Iran faces consequences if, or when, it violates the terms of the nuclear deal or United Nations sanctions.
