That is all irrelevant to the point I made. We are discussing the event of a war between China and the United States in North Korea. We are talking about what China would do if the U.S attacked North Korea. A war necessarily means that trade between the countries will stop. China loses all of the leverage you keep citing. The U.S has the productive capabilities to supplement a war-economy, which isn't focused on iphones and laptops, but on bombs and guns.  

My point still stands, China is not going to cut its second largest trade partner, for North Korea. The buffer zone and fallout from the dissolution of the North Korean regime are cheaper than losing trade with the United States and possibly expanding the war beyond North Korea (which would be a global catastrophe.) If the U.S attacked North Korea, China will likely secure/annex the border regions of North Korea and let the U.S take the rest. 

China don't want 30K+ US troops in their yard, they prefer to keep NK alive and keep those troops away from their borders.

the same justification that was used to destroy several nations in the middle east and kill millions of innocent people... and there are people here egging this on...

and then people wonder why there are "terrorist" attacks

what's funny about this whole situation is that supposedly its because north korean is arming itself with nukes....

the united states is the only country in the world to use a nuclear bomb on another country... and as i just said has been the country by a large margin most involved in perpetuating unprovoked attacks on other nations

If your neighbor beats his wife and kids every night and you know it's happening, do you just sit back and turn a blind eye? The US and the UN as a whole. feels it has a obligation to help defend those who can't defend themselves from power hungry leaders of other shitty countries who rule by oppression and fear. You can be the guy who watches your neighbor eventually kill his family or his family kill him. Or try to intervene and remove the issue from the situation. By any means necessary with a attack being the last resort. The US as a country has give more money to other countries as well as aid in many forms,then it does in its own backyard. 

Appease the madman.

Just promis him you wont invade, tell him he can stop threating, and or launching rockets.

Thats most likely all he wants anyways. Things carry on as they are, millions of innocent people dont have to die needlessly.

Alot of these nations out of favor with the US, all fear amercia starting wars with them, and invadeing them.

Thus they feel they have to get nukes, to diswade the US from doing so.

Hes nearly there, he can hit california already if he wanted.

Basically hes past the point where the US can actually threaten him and it mean anything.

Trump should know this, unless he wants to start a war with nukes, and millions of innocents dead.

Thus he should stop threatning them, which will just provoke them to do more missil launches and strive for even more advancements in that field.
