Two oil tankers near the strategic Strait of Hormuz were reportedly attacked on Thursday, an assault that left one ablaze and adrift as sailors were evacuated from both vessels and the U.S. Navy rushed to assist amid heightened tensions between Washington and Tehran.

Since the horror of the 9/11 attacks perpetrated by al-Qaeda and the emergence of the Islamic State, the U.S. has been fixated on preventing the next major terror attack. However, the focus is slowly shifting toward stopping lone-wolf attacks.

In repeating his readiness to pursue a new nuclear deal with Iran, President Trump this week left unmentioned his administration’s aim to hobble what officials call Tehran’s “expansionist foreign policy” — an ambitious priority that is far more likely to lead the United States into war.

Iranian President Hassan Rouhani signaled on Wednesday that talks with the United States might be possible if Washington lifted sanctions, days after U.S. President Donald Trump said a deal with Tehran on its nuclear programme was conceivable.

President Trump on Monday denied that the United States is seeking regime change in Iran, dialing back hawkish rhetoric days after ordering 1,500 additional U.S. troops to the region.
