Georg Simmel,
The American Journal of Sociology…
“ War brings them so forcibly into consciousness that its disturbances actually nullify the differences. Thus the condition which, so far as our present thought is concerned, makes war dangerous disappears in the presence of war. In case the attack is not sharp enough to overcome the enmities present in the group, war produces the above asserted effects. How often has war given the last blow to a state system suffering from internal disruption! ”
