Declaration still relevant
LOOKING AT THE POTSDAM DECLARATION 69 years after its release on July 26 in 1945 is of great help in knowing why the Japanese government's attitude toward the war of aggression it launched against China and other Asian countries during World War II matters a great deal to its relations with its neighbors and the situation in East Asia.
Along with Cairo Declaration in 1943, this historical document was the cornerstone of the postwar world order. It was these two documents that established the principles for Japan, one of the culprits for World War II, to redeem itself from the evils of its militarism. And it was by following what both documents stipulated that Japan could realize reconciliation with its neighbors, which had forgiven what its invading troops had done to their peoples with the hope that the island country would behave itself and contribute to the building of a peaceful Asia and peaceful world at large.
However, the declaration was challenged when the Japanese government made the decision to nationalize the Diaoyu Islands in 2012, territory it had grabbed from China with its military aggression. Japan was supposed to return all the territories it had taken from China according to Cairo Declaration, and the Potsdam Declaration requires that the Cairo Declaration must be observed.
