Washington - US President Donald Trump said on Thursday that military action against a defiant North Korea after its recent powerful nuclear test was "not inevitable."Speaking in a White House news conference along with the premier of Kuwait, the president said, "Military action would certainly be an option. Is it inevitable? Nothing's inevitable.""It would be great if something else could be worked out," he said, while adding that if it comes to military action, "It will be a very sad day for North Korea."AP reports that US President Donald Trump says North Korea "is behaving badly and it's got to stop."
