CarolC and Q:

I don't think there's anything inaccurate about what you're saying, but you are overlooking that unnecessary use of fuel raises prices and makes more money for the Saudis. This has side issues which are not bad, (such as it is good for us Alaskans). But the operative word is fungible. You can't 'not' buy from Saudi Arabia because they supply an equivalent gallon to someone who didn't buy it from whom you bought it.
