"If North Korea does anything in terms of even thinking about attack of anybody that we love or we represent or our allies or us, they can be very, very nervous", he explained.

He said President Trump was just trying to give the country's people hope when he floated the idea on Friday that the USA would take military action after condemning Venezuelan leader Nicholas Maduro for human rights abuses and calling for him to hold "free and fair elections".
Earlier this week, the Trump administration also imposed new sanctions on Venezuela, targeting members of the new all-powerful constituent assembly.

Tuesday: "North Korea, best not make any more threats to the United States", Mr Trump tells reporters.
