But the enemy in this war was fellow Europeans, sharing the same civilization, the same laws of war, more or less the same religion and outlook on life. &quot;Fraternizing with the enemy&quot; is only a problem if you&#x27;re a stuffy old archvillain like Haig or Ludendorff -- or if you&#x27;re fighting against an enemy with whom you really don&#x27;t have very much in common. (The Iraqi insurgents, for example, liked to wear plainclothes in battle, set up mortar plates in schools and hospitals, and fight while waving white flags.)
