Is it true that lust for gasoline is more powerful than love for your country?

It is a given fact that gasoline purchases by Americans results in direct revenue and weapons for islamic terrorists in the middle east who kill our troops and devise attacks on our country. This includes any sale of international oil from any other country because that is what drives up the prices for the terrorist-countries, including Iran, from whom we do not directly purchase oil. We know that by improving miles-per-gallon on average a few points, we would be free of non-domestic oil. Now, it is true that many people truly need large suv’s, or trucks, because of a business, for example land-scaping, or because they have 5 or 6 children, etc. But we all see the millions of suv’s, trucks, and sports cars that are simply used to drive back and forth from office jobs and the store, etc, a function that could easily be done with a hybrid-electric automobile (as I do with mine). So, do these people, truly just have a selfish lust and don’t give a damn about our troops and country?
