if every action is the result of another act, yes you are right.
every "choice" you make is dependant on other situations, and the "choice" isn't a choice at all - just another reaction.
i don't think that's a fair statement at all. we still bow to storms, earthquakes, volcanism, meteorites, etc. we may be able to kill other living species but Earth's natural processes are still more effective than any method of war.
