The United States and South Korea launched a three-week large-scale live-fire military exercise with the goal of completely annihilating the enemy, sending a message to North Korea to achieve peace with overwhelming force. More than 600 weapons including fighter jets, helicopters, drones, tanks and artillery from the US and South Korea participated, and a mountainside not far from the border was one of the targets. The media and hundreds of civilians were invited to observe. Experts believe that only a show of muscle can make Kim Jong-un think twice.
