Donald Trump has said countries which rely on the vital Strait of Hormuz shipping lane for oil should "build up some delayed courage" and "just grab it".The US president also said after the Iran conflict was over, the critical waterway would "just open up naturally".But while there were thinly veiled jibes at allies that had refused to take part in his offensive against Tehran, more strident criticism was missing from the American leader's 19-minute address to the nation.
