US Acting Secretary of Defence Patrick Shanahan said in a statement on Monday that the Pentagon has authorized the deployment of approximately additional 1,000 troops for defensive purposes “to address air, naval, and ground-based threats in the Middle East”.
The Pentagon has recently increased its forces in the Middle East. The US deployments in the region include an aircraft carrier strike group, Patriot missiles, B-52 bombers, and F-15 fighters, according to the US Defence Department.
On Thursday, two oil tankers – the Kokuka Courageous and the Front Altair – were reportedly attacked in the Gulf of Oman near the Strait of Hormuz. While the causes of the incidents remain unknown, the United States has accused Iran of allegedly sabotaging the vessels.
In the wake of the attack, US President Donald Trump ordered the warship USS Mason to be dispatched to the area, adding to the United States’ already significant military presence in the region.
Relations between Iran and the US deteriorated after Trump, an avid opponent of the Iranian nuclear deal, pulled out of the 2015 Joint Comprehensive Plan of Action in May 2018. The decision has been criticized by the other signatories of the nuclear deal: China, France, Germany, Iran, the European Union, Russia and the United Kingdom.
The US later unveiled new sanctions against Iran, targeting its economic, financial and transportation sectors, among others. The situation worsened when Iran announced on 8 May that it had partially discontinued its commitments under the agreement and had given Europe two months to ensure Iran’s interests were protected under the deal.
Iranian Supreme Leader Ayatollah Ali Khamenei said that Tehran would not negotiate with the US. Iranian President Hassan Rouhani, however, has not ruled out the possibility of negotiations with Washington if sanctions against Tehran are lifted and the longstanding US policy of oppressing Iran is abandoned.
