A few 10s of European people die at chernobyl = crisis, ban nuclear now. A few 10,000s of Indians die at Bhopal = so what.
Of course sometimes you have to be a little more discriminating. A damn breaks in China killing poor yellow people = so what. A reactor accident in Japan affecting rich yellow people = crisis.
Strangely 1800 people being killed on trains in a Tsunami doesn't seem to matter. Germany hasn't decided to cancel ICE services between Munich and Wien until the track can be made Tsunami proof.
