Iran has threatened that their navy will close the Strait of Hormuz if the Western countries want to impose sanctions against their nuclear programs, which has been meant only for peace and development. Iran Navy Chief has even said that closing the Strait of Hormuz will be easier than drinking a glass of water.
If the Strait of Hormuz can be closed, then it is bound to hamper the supply of crude oil to the entire world since about one-sixth of the crude supply of the world is trafficked through the Strait of Hormuz. US have instantly reacted to the threat and have claimed that the threat is nothing but a complete bluff.
US officials feel that Iran does not have the necessary naval strength to block the Strait of Hormuz, but they do have mine laying and missile throwing powers to create some havoc and that will be enough to bloc the flow of traffic in the zone. Analysts feel that if Tehran feels that they could create blockage and havoc, then it will not be an easy cakewalk for US.
Meanwhile, the US Fifth Fleet based in Bahrain posted nearby is keeping a close eye on the activities of the US naval fleet in the region. Any initiative of mine laying or missile activity will be detected and will be reversed back with a US response.
