It seems as though President Trump’s patience with Kim Jong Un has worn thin.

A breaking report today says that North Korea has now developed a “mini Nuke” that can fit inside a missile.

This is the last step that the world had been watching for, and may be the final straw that invokes a swift response from the USA.

In fact, President Trump just said North Korea will be met with “fire and fury”.

Take a look:

Here is more, from CNBC:

President Donald Trump on Tuesday warned North Korea about facing “fire and fury” if the isolated nation makes 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 … and I said they will be met with fire, fury and frankly power the likes of which this world has never seen before,” Trump told reporters during what he calls a “working vacation” at his New Jersey golf club.

His comments came hours after revelations Pyongyang has successfully created a miniaturized nuclear weapon designed to fit inside its missiles.

The development raises the stakes for Trump and other world leaders, who already faced difficult and limited options in dealing with North Korea’s aggression.

The U.N. Security Council on Saturday unanimously put new sanctions on North Korea over its continued missile tests. The country has tested two intercontinental ballistic missiles that landed off the coast of Japan this year. Some analysis has said one of those missiles could potentially reach the mainland United States.
