I would certainly hope not. You give these animals an inch, and they take a foot, along with your life, and the lives of your loved ones. And then you're demonized in the media, and by the U.S. and European governments for protecting your borders, and your people.
That is why, even in war, we treat the enemy respectfully. Because we know that there will be a time when we are not at war. And getting to a time of peace happens quicker if there is mutual trust and respect... even though we are doing the best to kill each other.
These people are ruled by savagery and cannot be trusted.
