The stone beneath your feet belongs to Thailand; the ancient temple ruins visible just across the ridge belong, by ruling of the International Court of Justice since 1962, to Cambodia. Between these two facts lies a story that has never been fully resolved, a boundary that nations and armies have argued over for decades, and a landscape of dry forests and carved sandstone that has outlasted every dispute so far.
