Why would they, the only ones restricted from pumping oil are Americans, just look at the Gulf of Mexico, everyone else can exploit it but us. The only thing to remember is that Americans are incapable of using natural resources wisely, unlike everyone else in the world. Remember Captain Planet and the Planeteers? They were led by a Russian! Led by someone from a country that dumps nuclear waste in their coastal water, not by a filthy eco criminal American!
The North Dakota Oil Boom probably wouldn’t had happened if it wasn’t for property rights.
