I'm hearing a news that N.Korea shot 100+ missiles at S.Korea at my hometown(Exact town that I was born)
Will Korea have yet another war? If they do, what'll gonna happen?

I'm in Asheville now, so I won't get hurt.

Nah. I'm 16 so they won't call me. I just hope that it won't happen..
I wish my hacking skill is so good that I would be able to rickroll Kim Jung-Ill in his face

ah ok. I should learn to be serious.

N.Korea has always seemed to be unstable.
Expect anything is what i say, but don't lose faith in humanity.

Wow i sound corny...
But serious.

If Korea fights the war....
-US involve
-China involve
-Muslim attacks Jews at Middle East
-Nuclear war
-You'll see real version of FallOut3

I have a bad feeling about this.  Korea is back at war, even if it isn't formally acknowledged, and the big problem is China.  They sit in a very bad position right now.  The United States owes China a lot of money, so they are less likely to back us, and by extension, South Korea.  However, if they were to side with North Korea, they have way too much power, and South Korea will collapse into North Korean rule.  However, if China supplies North Korea with more weapons, there will be even more problems, especially if the weapons are nuclear.  China has a history of expansion, and has not always been the nicest.  North Korea is led by an insane dictator, not to put too fine of a point on it.  If they combine, there is a strong chance that the world can fall under their combined feet.  North Korea might be the excuse China needs to take control, and believe me, China has the resources to take over the world, and North Korea has the insanity to consider it.  South Korea would only be the beginning.  Nuclear war will be the only option for the US, though we will consider it very deeply.  We can't stand up against China without nuclear weapons, and even then, it's not likely.  But the moment we shoot ours, they shoot theirs.  Mutually assured destruction.  That is the worst case scenario, if China sides with North Korea.  Making matters worse, China has a history of supporting North Korea, and is already performing displays of power with them, same as we are with the South Koreans.  I feel that China has already decided, but I hope for the betterment of the world that they hold onto their nuclear weapons.
The best option would be for China to side with South Korea.  I don't necessarily think that North Korea needs a revolution, but I wouldn't be entirely opposed to the collapse of the dictatorship.  I don't think South Korea wants to take over, either.  But the Korean War never really ended.  There was a cease fire, but they never officially ended the war, and have been harboring resentment ever since.  Both sides are thirsty for revenge.
The next best option would be for China to remain isolated from the conflict.  They have already interfered, but they can always pull out when the shit hits the fan.  South Korea would win with our support, unless of course North Korea's claims of nuclear capabilities are founded in fact, in which case they will fire them at South Korea, and force some very hard decisions for world leaders everywhere.  However, I don't believe any of this paragraph is true.  China has already shown their support for North Korea, and I doubt that North Korea has nuclear potential on their own.
The best option by far is for the shows of power on either side to work, and for one of the countries to blink.  If this happens, we can hope that the other country will stand down.  The tension of a month ago is not ideal, but it is better than the full out war we could be facing today.  No matter what happens, I have a sickening feeling that this will leave a scar across the entire world's history, not just Korea's.

tl;dr: If you can, please get out of Korea.  I doubt it will be safe there for long.

isn't Asheville in korea?
