SEOUL - North Korea has backed presumptive US Republican nominee Donald Trump, with a propaganda website praising him as 'a prescient presidential candidate' who can liberate Americans living under daily fear of nuclear attack by the North. A column carried on Tuesday by DPRK Today, one of the reclusive and dynastic state's mouthpieces, described Trump as a 'wise politician' and the right choice for US voters in the Nov. 8 US presidential election. It described his most likely Democratic opponent, Hillary Clinton, as 'thick-headed Hillary' over her proposal to apply the Iran model of wide sanctions to resolve the nuclear weapons issue on the Korean peninsula.
