This is one of the reasons that invading countries whose cultures are alien to you tends not to work.

Unlike the armchair warhawk crowd, I don't really have any delusions about the likelihood of peace in the Middle East while foreign powers are using military force to occupy nations such as Iraq or Afghanistan.

As the Soviets learned in the 1980s, an entrenched resistance that has roots in the local culture is next to impossible to ferret out - especially when you grok neither the culture nor the language of those whom you are trying to occupy.
