How high do gas prices have to get before NATO/USA begin to consider adding colonies?

What right has the US to oil in other countries? What gives the US or Europe or whoever the right to expect oil should be provided for less than market price? And market price is determined by the laws of supply and demand. The reality is that the world is facing high prices largely because supply is lagging behind worldwide demand (in turn largely driven by China and India), oil is increasingly expensive to produce and stability of supply increasingly problematic.

Experts have been warning about US dependence on foreign oil and "Peak Oil" (when half the world's oil has been used up and supply starts to decrease) for years. No-one wanted to listen, but it's starting to have the predicted effect. Get used to high oil prices and hope the real problem ... rationing ... isn't next.

As to anyone trying to control oil supply someone might try, but it won't succeed. the supply chain is too fragile and anyone trying to control it will simply cause damage that will cut supply even more.
