Japan is the only country in the world with a "no war" clause explicitly written into its constitution. But, thanks to the shenanigans of its neighbors, the Japanese are being forced to make a U-turn.
North Korean dictator Kim Jong-un has kept the world on its toes with his flurry of missile tests. In October of this year, Pyongyang launched what it described as "the world's most powerful weapon." The ballistic missile, launched from the port of Sinpo in North Korea, landed in the East Sea, also known as the Sea of Japan. North Korea has brought Japan within striking range of its weapons with its latest exploit.
Japan and China have a strained, often contentious, relationship. Beijing's claims to the South China Sea and the region's numerous islands and atolls, based on "historic rights," are a major source of friction between the two countries. In the past decade, Beijing's efforts to take back the Senkaku/Diaoyu islands have prompted Japan to act swiftly and methodically. The eight pieces of land, covering an area of 7 km, are expected to contain potential oil and natural gas reserves and are located next to major shipping routes. The U.S. has explicitly stated that the Senkaku/Diaoyu islands come under the U.S.-Japan Security Treaty. Should tensions escalate, America will be drawn into the fray.
