The time for "strategic patience" with North Korea is over, US President Donald Trump warned on Monday, after winning Japan's backing for his policy of considering all options to rein in the rogue state. Trump described the North's nuclear programme as "a threat to the civilised world and international peace and stability" on the second day of his Asia tour dominated by the crisis. The President has signalled in the past that Washington could look beyond a diplomatic solution to the North's nuclear weapons ambitions and consider military intervention.
