But Trump, who had rubbished the agreement as the ‘worst deal’ even during his presidential election campaign, withdrew from the JCPOA that his predecessor Barack Obama had signed on in May 2018. The situation, however, worsened further from May 8, 2019, the first anniversary of the US withdrawal from the Plan of Action, when Trump decided to reimpose sanctions on Iran. Soon after, four oil tankers (including two Saudi ships) were attacked in the Gulf of Oman by unidentified sources that the US and its allies suspected to be Iranian ‘proxies’. Reacting to it, the Trump administration announced the movement of USS Arlington—that transports US marines, vehicles and other military hardware (helping in amphibious assaults)—and a Patriot battery to the area along with 1,000 troops. This is in addition to the 15,000 soldiers stationed in West Asia in the Central Command (CENTCOM) that looks after US interests in the Gulf.
