President Donald Trump issued an extraordinary ultimatum to North Korea on Tuesday warning Pyongyang not to make any more threats against the United States or they will "face fire and fury like the world has never seen," during a photo op at the Trump National Golf Club in Bedminster, New Jersey.

"North Korea best not make any more threats to the United States. They will be met with fire and fury like the world has never seen... he has been very threatening beyond a normal state. They will be met with fire, fury and frankly power the likes of which this world has never seen before," he said.

Trump's harsh words come as US intelligence analysts have assessed that North Korea has produced a miniaturized nuclear warhead, according to multiple sources familiar with the analysis of North Korea's missile and nuclear program.

It is not believed that the capability has been tested, according to the sources.
This is not a consensus view from the entire intelligence community, one US official said. The Washington Post, which was first to publish details, reported that it was the analysis of the Defense Intelligence Agency.

The US official familiar with the analysis of North Korea's missile and nuclear program says, in reference to North Korea's leader Kim Jong Un's boasts about the program, "we have to take him at his word and we need to be prepared to deal with it."
This official said the 'assessment" is continuing to be refined and updated as more intelligence is collected.

The officials all note that the evidence shows North Korea is making progress and the question is more about when not if North Korea is capable of launching a nuclear capable missile.

Referring to Kim Jong Un, the official said this report needs to be taken seriously as "we've seen him moving forward" on the program with no indication he is turning back.
US military commanders have long planned on the assumption that North Korea has a warhead.

In 2014, then-commander of US Forces Korea Gen. Curtis Scaparrotti said he believed that they had the capability to miniaturize a warhead.
"I believe they have the capability to have miniaturized a device at this point, and they have the technology to potentially actually deliver what they say they have," Scaparrotti said at the time.

The Washington Post first reported details of the assessment on Tuesday just hours after North Korea threatened 'physical action' in response to punitive sanctions unanimously passed by the United Nations Security Council over the weekend.
