US president says Pyongyang 'is behaving badly and it's got to stop' as officials eye policy of nuclear containment.
An American military strike on North Korea is not inevitable, US President Donald Trump said, but it would be "a very sad day" for the Asian nation if it ever came to fruition.
Trump also said North Korea "is behaving badly and it's got to stop". He was speaking at a White House news conference after meeting the leader of Kuwait on Thursday.
"Military action would certainly be an option. Is it inevitable, nothing's inevitable. Hopefully we're not going to have to use it [military action] on North Korea. If we do use it on North Korea, it will be a very sad day for North Korea," he said.
Trump, like his predecessors, may find neither negotiations nor economic and military pressure can force North Korea to abandon its nuclear programme, and the United States has no choice but to try to contain it and deter North Korean leader Kim Jong-un from ever using a nuclear weapon.
