Island of Yeonpyeong have been disputed between the two Korea's for years, having some naval skirmishes here and there. But now this has escalated to a whole other level, South Korea is scrambling their F-15 and F-16 Fighter Jets, in case this situation escalates. North Korea is just flexing their muscle, having a GDP of 27 billion dollars, 10 billion of it going to maintain their army. With their economy in shambles, and spending almost half your GDP on army that's just on standby. Might as well act on some threats they've been saying over the years, now they have the Worlds attention. Well see how this progresses but in the end. North Korea will not fall, or Chinese will have influx of backlash immigration of North Koreans in their country, as well as having a U.S presence at Yalu River (Chinese Border).
