Fools with an impotent understanding of geography would do well to remedy that deficit.
Kashmir is a large, Texas-sized state in India with the terrain containing the width of the Greater Himalayas. The advice was not meant for people at Ground Zero, but the surrounding areas which will suffer limited damage only, due to the terrain.

Excellent post, brimming with facts about Kashmir territory.
