All of the oil in Norway is owned by Norwegians.
All of the oil outside of UK is owned by British companies.
All of the oil fields in Saudi Arabia is owned by Saudi Arabia.
All these countries have been able to build up their economies due to their nature resources, all three are reliable allies of the USA.
Nigerian oil fields are mostly owned by foreign companies, leeching the resources out of the country.
Nigeria is poor. The government and society is fragile.
IMO, any country who doesn't control their own nature resources, has to nationalize them.
It's imperative to get all the earnings of the nature resources back to the country where it all originates from. These countries have to be in sovereign control of their own resources.
Necessery for development of peace, democracy and global wealth.
