In a surprising bit of fallout from the recent warming trend in relations between the India and Pakistan countries, their respective border patrols -- the Pakistan Rangers and the Indian Border Security Force (BSF) have concluded a memorandum of understanding to regulate operations along the often convoluted, ill-defined, and contested frontier between the two countries. This memorandum was concluded by officials working for the heads of the respective forces, rather than by members of the governments of the tow countries, though they certainly approved. The agreement covers such matters as how to deal with inadvertent border crossings, cross-border criminal activities, and, though apparently not directly stated, terrorist movements.
