As nice as that sentiment might be when oil prices go through the roof the last thing on Americans' minds will be the meddlesome nature of US foreign policy or the cost of wars. If the situation is allowed to persist for any length of time other superpowers will insist that either the US take action or they be allowed to do so. Then we might have multiple superpowers occupying the region and vying for position.
Make no mistake about it, Rome has suffered a major setback and chaos is now breaking out in the conquered provinces. If the supply of oil is disrupted enough for other superpowers it could lead to another world war. Although the history books don't like to mention it, the Japanese attacked Pearl Harbor shortly after the US imposed an oil embargo on them. Desperate people resort to desperate acts.
