Agree there. But remember “operators” includes the local Indian management that didn’t care at all about safety.
The local management should have been hung out to dry as they were directly, criminally responsible.
American management should be held for their failure to properly supervise the locals, and they have already paid millions for that.
You can't just plunk a facility as dangerous as the Bhopal plant in a foreign country and assume things will work out. The oversight should have been much, much more stringent.
To Union Carbide's credit, they built all of the right equipment. They just didn't do anything about it when it was not operated or maintained properly.
