This is what will happen if North Korea attacks the USA

North Korea's leader Kim Jong-un has finished reviewing a plan to fire four missiles towards Guam.

This has obviously raised a few eyebrows, given North Korea's recent forays into nuclear capabilities and escalating tension between the rogue state and President of the United States Donald Trump.

The official media agency for North Korea, KCNA, said of Kim Jong-un:

He said that if the Yankees persist in their extremely dangerous reckless actions on the Korean peninsula and in its vicinity, testing the self-restraint of the DPRK, the latter will make an important decision as it already declared.

A White House statement early on Tuesday said:

President Trump reaffirmed that the United States stands ready to defend and respond to any threat or actions taken by North Korea against the United States or its allies, South Korea and Japan.

South Korean President Moon Jae-in said on Tuesday there would be no military action without Seoul's consent:

Military action on the Korean peninsula can only be decided by South Korea and no one else can decide to take military action without the consent of South Korea. 

The government, putting everything on the line, will block war by all means.

Reddit has weighed into how nuclear war could affect the planet.

Many users have gathered to prophesy the future of humanity, becuase it's the internet.

Here's what they have to say:

In short, the consensus seems to be that South Korea is heavily bombarded by North Korea's conventional artillery, and North Korea fails to deal with United States countermeasures.

These comments are in no way expert opinion, and largely do not take into account alliances, treaties and cannot predict the future, so the whole thing is moot.

No one really knows how nuclear war would affect the planet, or how a conflict using conventional missiles between the Korea's would go down.

For a rough outline, read this rundown by Quartz.
