Let's break this down:
There really is "no hope" for us if we follow this so called rules of war bull ****!
There really is "no hope" for the extremists if we say **** the rules we are going to win!
Certain rules really do not need to be adhered to or we will lose this. I'm sure you're not naive enough to think that if we follow a "set of rules" our opponent will do the same and the end result will a lot of blood shed from both sides with one winner and one looser. But hey, it will have been a good fight and the winner will celebrate a triumphant victory safe in the knowledge they strictly followed the rules of war and won fairly! Do you think the winner of a street fight is the one that follows a set of unwritten rules? Or the one that kicks his opponent in the balls, then goes for the eyes and the throat - I know what one I'll be in that situation.
WE HAVE ALREADY LOST.
God, some people are blind, the very fact that the rulebook doesn't always get adhered to is EXACTLY why we have lost.
This is not a war of force, it is a war of societies and if we continue on this route, we wont have one left to protect, just some dystopian nightmare, that is exactly what they want and you'd hand it on a plate to them.
