The escalation of military action poses a security risk to Iran, the United States and other Gulf countries that may be involved in a military conflict. Hopes for a peaceful solution to the crisis are slim, as neither side appears ready to resign. However, for this crisis to be resolved without violence, both sides must reach agreement and mutual understanding. On April 28, 2015, IRGCN patrol boats contacted the Marshall Islands-flagged container ship Maersk Tigris, which was crossing the strait westward, and ordered the vessel to travel to Iranian territorial waters, a U.S. Defense Department spokesman said. When the ship`s captain refused, one of the Iranian ships fired on the deck of Maersk Tigris. The master complied and went to Iranian waters near Larak Island. The U.S. Navy sent planes and a destroyer, the USS Farragut, to monitor the situation.  With regard to the Strait of Hormuz, Iranian Defence Minister Amir Hatami stated that „we have the power to protect our vital interests in this strait and to make the necessary decisions in time.“ He added that in addition to naval capabilities, „we have other forces, including missile power and a few others, so that we can make the necessary decisions in a timely manner and implement them strongly.“ After the United States withdrew from the international Iran nuclear deal, Tehran said it would not negotiate another deal with Washington. The Strait of Hormuz (/h`r`mu`z/ Persian: and Tangeh-ye Hormoz -Audio (Helpinfo) Arabic: „Maq Hurmuz“ is a strait between the Persian Gulf and the Gulf of Oman. It offers the only sea passage from the Persian Gulf to the open ocean and is one of the most important strategic choking points in the world.  On the north coast is Iran and on the south coast is the United Arab Emirates and Musandam, an Omani enclave.
The strait is about 167 km long and has a width of about 96 km to 39 km.   This 21-mile canal connects the Indian Ocean to the Gulf. For all recorded history, it has linked Arab and Persian civilizations to the Indian subcontinent and Asia Pacific. Thus, before the rise of the European maritime empires in the 15th and 16th centuries, china and spices from the Indochinese peninsula often crossed the strait on the way to Central Asia and Europe. The U.S. Navy, referring specifically to the Persian Gulf, the Gulf of Oman and the Arabian Sea, advised that „due to recent events, in order to enhance security, minimize ambiguity and reduce the possibility of miscalculation, all vessels are advised to respect a safe distance of at least 100 m from U.S. Navy vessels in international waters and straits. Armed vessels approaching a U.S. Navy ship within 100 metres can be interpreted as a threat and subject to legitimate defenses. An Iranian military official went on to say that „the naval units of the Islamic Republic of Iran in the Persian Gulf and the Gulf of Oman will continue their regular missions according to professional principles as in the past.“ Instead, Britain declared that it would commit the same two warships it had previously tasked to escort British-flagged ships across the strait to the US-led mission. Britain and the United States are the only two countries to contribute to these efforts. The temporary agreement applies to operators of a vessel which, due to the transit of the UNITED Kingdom flag area and the Red Ensign Group, does not take into account the relevant guidelines of interprofessional organisations such as OCIMF, INTERTANKO, BIMCO and ICS, and does not accept the advice of the flag state.
