So over the "protection of financial interests" (the oil wells) you think intervention was a benevolent attempt to keep the area stable.
Have you met "people"?
If you are suggesting, in the global backdrop post WW2, that Iran and the surrounding areas were going "tits up" then I think you are arrogantly downplaying what went on in the Western World during WW2, such as, but not limited to, Hiroshima, and The Holocaust. By any standards, things were quite a lot more civilised and humane there :P
