UK Prime Minister Keir Starmer Friday denounced as "insulting" Donald Trump's claim that troops from NATO allies avoided the front line in Afghanistan, as anger grows at the US president's remarks. In an interview, Trump appeared unaware that 457 British soldiers were among NATO troops who died during the conflict in Afghanistan following the September 11, 2001, attacks on the United States. "They'll say they sent some troops to Afghanistan," Trump told the US outlet, referring to NATO allies. "And they did, they stayed a little back, a little off the front lines," he added, triggering outrage across the political divide in Britain. Trump also repeated his suggestion that NATO would not come to the aid of the US if asked to do so.
