Donald Trump is poised to order a military strike against North Korea ‘within the next year’ after the communist state said it had successfully fired a ballistic missile capable of hitting the US mainland.

Senior military sources in Washington DC told The Mail on Sunday that Pentagon officials have laid out plans to obliterate a nuclear weapons facility operating deep within a mountain in the rogue state.

The move, which could spark retaliation attacks from dictator Kim Jong-Un, would be a major step towards all-out war to stop North Korea from developing nuclear weapons. It comes after North Korea fired an intercontinental ballistic missile with a range of 6,500 miles on Friday night.

The Pentagon said the missile flew about 2,300 miles almost straight up before plunging into the sea off Japan about 620 miles from its launch site.

Experts in the US said the missile could have hit Chicago or even New York if it had been launched on a flatter trajectory.

Kim Jong-Un claimed the whole of the US could be hit ‘at any place and time’.

America responded with live firing exercises by US troops in South Korea yesterday. President Trump vowed to ‘take all necessary steps’ to ensure the security of the US and its allies.
