US President Donald Trump amused his cabinet members by mimicking the sound of American anti-aircraft interceptors taking down Iranian ballistic missiles. “Bing, bing, bing, bing, bing. I don’t wanna be Biden. I had to be very careful. That would have been a great soundbite,” Mr Trump said. “There were five missiles, and we shot all five down before they got close. Nobody else has that capacity. “These weapons are incredible.”
