What are the political problems with the exploitation of crude oil?

Well, the problem is... there is just some countries in the Middle East who are oil-producing. Think about it like a spoilt kid; she has angel cakes which you really want. Except she won't let you have some unless... you pay her and the more you get, the more you want. She keeps raising the price of the "cakes" and you don't notice until... BAM!! You're out of money.

It's exactly the same with oil- nations fight with bare knuckes and fists for the stuff.
