The discovery of oil comes with a huge blessings capable of transforming individual lives communities, states and even countries if well managed. But a situation where the proceeds are miss managed it will turn to be a cause as individual will rise against individual, states Wil rise against starts, countries will rise against countries.
OP, this forum thread is so random. Is there any reason why you decided to post this forum thread? Do you live in a country or a region where oil was recently discovered? I don't remember any countries around the world fighting against each other for oil in the last several decades.
Oil discovery was a blessing for the small countries in the Persian Gulf and for a small country like Norway. Other countries that have big oil reserves like Russia, USA, Nigeria and Venezuela aren't that rich(maybe except the USA, but that's another topic).
The world will slowly move towards alternative forms of energy in the upcoming several decades. The oil dependency of the global economy is going to decline slowly.
