A few years ago I was lucky enough to visit a remote border outpost in Arunachal Pradesh where a sentry sat in the thick morning mist, pierced only by the gentle flares of flowering rhododendron bushes. His binoculars were trained on a Chinese outpost perhaps a hundred yards away. This place had been a minor flashpoint in the 1980s when the Chinese established their camp and started building a helipad. The Indian army set up its own posts on higher ground. Things calmed down, so I was told, when the People’s Liberation Army clarified that the helipad was really a basketball court. The jawan’s job was to watch basketball and he took it very seriously.
