North Korea won't go to large scale war with south Korea.
The reason they are firing is to threat the western country , for more international supply and aid. Like food and basic human needs.
2nd, many people are thinking mr. Kim wants his son to gain some military stats for being tough and attacking south Korea. After all mr. Kim is getting old with illness. He wants to power level his son before he dies.
and china will always support north korea
1)communism brotherhood, eventho big brother russian went down
2) north korea is the gate to china when it comes to milatry invasion from the east, ie japan.. check out the map. china doesn't want the gate to go down. u can say ppl can come from other direstions. well u got the mountains from india, ppl doesn't come from the poor countries from south, and china got his ex-brother russia on top. u have the pacific ocean from the east , except japan. so north korea is a very impoartant peice of land to protect.
now do u still wonder why north korea can last for so long when the big american are so damn powerful for so many decades? look at middle east,, takes couple years and all thier black gold are all taken, pumping like no tml.
