In Germany you are not even allowed to print "Soldiers are murderers" on your T-shirt, which makes me angry every time I think about it. How about "historically and statistically soldiers have a tendency to be rapists, torturers and manslaughterers"?
1. Assuming that under a just war theory, a just war can AT MOST be just for one of the warring sides
2. big armies aren't any more likely to fight just wars than small armies
We can conclude that if you're a soldier in a war, there's a better than even chance that it is unjust, and deserters are on average more honorable than soldiers."
