US President Donald Trump said Saturday he had called off a secret summit with the Taliban and Afghanistan’s leader, abruptly slamming the door on a year of diplomacy to end America’s longest war. In a Saturday evening bombshell, Trump said that he had planned unprecedented, albeit separate, talks with the two sides Sunday in Camp David, the presidential retreat in Maryland, but that the Taliban’s persistent, grisly campaign of violence made them untrustworthy partners. “Unbeknownst to almost everyone, the major Taliban leaders and, separately, the President of Afghanistan, were going to secretly meet with me at Camp David on Sunday,” Trump said in a tweet.
