A soldiers definition of war is probably killing the enemy by fair means or foul. As regards nail bombs was frequently used during Nelsons era by the navy in lieu of cannon balls, until more sophisticated weapons came there are more than two sides to any conflict nowadays. So we go back to the good and the bad, and adjust this by saying we are on the good side. Depends what propaganda one is able to put out. There are always atrocietys in war to name a few was the use of Napalm in Vietnam also agent orange, what other methods of killing is probably kept under wraps. To fight wars over religious beliefs is going back to Crusader times with the same mindset. The quickest results is for every Christian country to outlaw Sharia law, however this might step on the toes of those who believe religion and all its teachings are sacred, and above man made laws. Everyone has his or her personal beliefs, if we didnt and not make them known, you are only giving free rein to whoever is head of the country, by definition Politician or Dictator. JS
