"The President has made clear that he will not accept the US and its allies and partners in the region being under threat from this hostile regime with nuclear weapons. And so we're working together with our allies and partners, and with the Chinese leadership, to develop a range of options," national security adviser H R McMaster said.
McMaster said the latest missile test, which failed, just fits into a pattern of "provocative and destabilising and threatening" behaviour on the part of the North Korean regime.
"I think there's an international consensus now, including the Chinese leadership that this is a situation that just can't continue. The US President has made clear that he will not accept the US and its allies and partners in the region being under threat from this hostile regime with nuclear weapons, he told ABC News.
McMaster said President Donald Trump has asked the National Security Council to integrate the efforts of the Department of Defence, State, and intelligence agencies, so that they can provide options and have them ready for him if this pattern of "destabilising" behaviour continues.
"These options would be used if North Korea regime refuses to denuclearise, which is the accepted objective of both the United States and Chinese leadership, as well American allies in the region," he said.
"I think what you saw last week with the President's decisive response to the Assad regime, to mass murder of innocent people, including children, with chemical weapons, that this national security team is capable of rapidly responding to those sorts of crises or incidents and events and providing the President with options. And our President is clearly comfortable making tough decisions and respond, he said.
All our options on the table undergoing refinement and further development, the top American national security advisor said in response to a question.
McMaster said it should make clear to the North Korean regime that it is in their best interest to stop the development of these weapons, to stop the development of these missiles, and to denuclearise the peninsula.
"While we do not want to telegraph in any way how we'll respond to certain incidents, it's clear that the President is determined not to allow this kind of capability to threaten the United States. And our President will take action that is in the best interest of the American people," he said.
McMaster said what Kim Jong-un is doing is a threat to all people in the region and globally as well.
