Gideon...when you, and I'm paraphrasing here, ask when does one "free" being have the right to decide the doing or life of another "free" being. Well, when I live in a country a little over 8,500 sq miles and I'm surrounded by four other heavly populated same race nations that identify with my enemies that have tried to eliminate my people for more than just the past 60 years. It breaks beyond the question you ask and realms into the evolutionary or God given right/instinct to do what it takes or whatever it takes to ensure the safety and more so the survival of my family. Now I now you can argue and debate to the same outcome that they have a right to be here just as much or more so than us. So the truth of the matter, after putting aside all the politness and political correctness, is that really...really when the smoke clears all that will matter is who and whos family will remain. And I can pretty f***ing well garantee we will do our best that it will be our children to see peace.
