Since The U.S discovered fracking, a way to get petroleum, the cost of this useful materials are going down. This discovery has winners and losers. The losers are Venezuela and Russian for example. They are consider losers because they are biggerest provider of petroleum of the world. basically now their economies are going down hill, just like the prices for petroleum. The winners are The U.S., Spain and many other that use their income to buy petroleum.
You can see this from two different perspectives, first you can it as a conspiracy against enemies of The U.S, or you could see this as an opportunity
As many of you know Russia is a strong militar power and their main production is petroleum. Well, since U.S found franking, it is slowly destroying Russia. Since Russia is losing that money, they will not be able to sustain a war. Therefore The U.S. has the advantages, but this does not means that Russia will wait patiently wait while their economy goes down.
Many companies and countries buy petroleum because they do not produce it. Therefore their income is limited. Since the U.S had created this method, which is very expensive, they can produce petroleum as much as the land can. This means that the prices for petroleum will be very low and the money will go to them, this means that Russia will have less money than ever before and companies will grow more than before.
