If it weren't for the USA, we wouldn't have a petrol industry. They set it up in the 1920s, built all the infrastructure, helped with technology, trained all our excellent engineers (until 2000) and ensured efficient business methods. Oh, and they also bought most of it at international prices.
Currently, we give away 500,000 barrels to Cuba and Nicaragua, and the rest is cut price to the Chinese, the Iranians and the Russians. The Chinese are also destroying the Amazon jungle hunting for gold, and milking us dry of rare earth elements, thanks to government complicity.
