It would seem to me that we should kill them where they live, whatever the country, and make their bloodline suffer the same inhumanity that they themselves suffer upon Jews and Christians.
Just my two cents, but if their families can openly exist and they have sworn death and destruction upon our society, lets began the charity where it belongs - at home... for this movement and its bloodline. Cut the ties and pretty soon all is left is the head of the snake itself. Visit death and destruction upon family and country and it ends. Leave living their offspring and it will raise its ugly the next generation.
You are on to something there - muslims do not care how many fighters die - they have already chosen death. Kill their families and watch them run. Turn Mecca to glass and watch them go looking for a new religion...
