I agree with Louie to a point. We do have enough reserves to be self sufficient for decades to come. But then, why should we use ours when we can use theirs. Let them exhaust their reserves first and then see who is better of. Reducing our imports from Opec would not reduce the price. The demand is well beyond the offer, and if Opec loses us, they will find other markets to sell their oil and will not be affected by our withdrawal.
What I would suggest is to initiate a campaign of national pride and institute a weekly oil free day, when no Americans would buy a single gallon of gas. By reducing the demand, the price would definitely go down.
There are many problems we can fix if there were a little more pride and consensus among Americans.
