Maybe you misunderstood my point. I'm not giving the Saudis a pass. I would object to anyone doing this whether it is the Saudis, the Rockefellers, or some middle class farmer. The problem here is a poorly constructed regulatory environment which created a tragedy of the commons situation. We made it profitable to do something that is bad for the local environment and inherently stupid. People shouldn't grow water intensive plans in the desert.
The problem here is "company draws unlimited Arizona ground water amid drought". There doesn't need to be an adjective before "company".
