And just days later, North Korea enraged the US with a missile test - although the launch was deemed unsuccessful after it exploded almost immediately.
In response, Mike Pence warned Kim Jong-un the US would "defeat any attack" - but Kim Jong-Un retorted it would be a "piece of cake" to nuke Japan.
And North Korea threatened to nuke Trump's hometown of New York after he mocked the missile programme.
In August, Trump warned North Korea faces “fire and fury” if Pyongyang threatens the US or its allies as North Korea said it would launch four rockets towards Guam.
And on September 3, Kim Jong Un detonated a nuclear device which triggered an artificial earthquake six times larger than any previous test.
