Oscar You are right. In the west, we have only begun to understand that we are at war, a war conducted over centuries. It's an ugly thought.
It's a hard thing to realize that others want to kill you, but, that they do.
Break the "Sensitivity Barrier" It's what they depend on. Ask personal, intrusive questions, and watch carefully the re-action. If it's feigned offense, that's a defense, as example.There's much more, but you learn as you go.Keep in mind the concept of the 'tell' it's reliable.Don't listen to what they say, but rather watch what they do. And when they have revealed themselves ( they will, always, for they operate out of pride, their last defense,) well, hit first, and hit hard, and keep hitting until they are down, and down for good. Keep the Faith.J.OM.
