Joe Biden has said he stands "squarely" behind his decision to pull US troops out of Afghanistan and that America's role there "was never supposed to be nation-building". The US president gave a defiant briefing at the White House on Monday after the planned withdrawal of American forces turned deadly at Kabul’s airport. In his first public remarks on Afghanistan in nearly a week, Mr Biden said America's initial aims when entering the country 20 years ago were to prevent Afghanistan from becoming a haven for terror plots and also to "get" those responsible for 9/11. Mr Biden said the US completed these missions a decade ago, when they killed Al Qaeda leader Osama Bin Laden. • Subscribe to ITV News on YouTube: http://bit.ly/2lOHmNj • Get breaking news and more stories at http://www.itv.com/news Follow ITV News on Facebook: / itvnews Follow ITV News on Twitter: / itvnews Follow ITV News on Instagram: / itvnews
