Tensions have ratcheted up in the past week between the US and Iran following the killing of Qasem Soleimani. On Wednesday, Iran blasted missiles at two military bases in Iraq where US troops were stationed. A day later, tensions appeared to recede. In a televised address from the White House, Trump said Iran “appears to be standing down”. He even suggested that the US was open to negotiations with Iran. Is the crisis now over, or is there more to come?
