gee I don't know . . . maybe its possible that it buys it from another country?
exxon buys more oil than it produces,and it buys that oil at a market price, which, as I have already shown evidence of, has an 88% chance of being bought by a previously mentioned national owned foreign oil company
the facts are all there: western oil is small potatoes, western oil buys from foreign oil
until i see actual published evidence elsewhere, i don't see what else can be discussed
