Tom, Tom, Tom. If 3rd-world people were sub-human, your way might work.

They are just like you and me. If one takes that into account, one can beat an insurgency.
If one continues to treat them as a bit more than dogs and a lot less than human, you get the results we have right now.

I don't know about surrender. But you are very familiar with failure.
