There isn't a legal regime to enforce regulation and make people accountable, so the United States will not force American executives to comply with Indian laws in the case of Bhopal.

Bhopal was a more dramatic example but this sort of thing happens every day all round the world--a lot of them are unseen disasters, even right here in the Bay Area people are poisoned by industries. It's a slow death--heart problems, respiratory problems, and cancer. You don't see people die overnight but the toxic effects of major industry are felt worldwide.
