With 18 days to go before the end of the Trump administration, the US Secretary of State has threatened North Korea with maximum pressure.

Iran PressAmerica: On Saturday, on his official Twitter page, the US Secretary of State Mike Pompeo wrote: "The appeasement with North Korea has not worked and the United States must try a new issue through maximum pressure."

Washington's new threats against Pyongyang come as North Korean and US leaders signed a vague 2018 nuclear disarmament agreement in Singapore in exchange for lifting Washington sanctions, which has not yet been implemented.

The US President Donald Trump and North Korean leader Kim Jong Un met in Vietnam on the Korean border, but the talks failed due to Washington's failure to meet its commitments to Pyongyang. 219
