You know, it's easy to be idealistic when you're talking about stuff that you only see on television. When it affects you personally, all of that goes out the window and you're purely in survival mode. Believe it or not, war IS an answer to problems when the interests of two opposing sides are mutually exclusive (i.e. one side wants you dead, and you want to not be dead). Or, to put this in terms you might understand... how many times did Captain Kirk (and don't get me wrong, he is still my favorite captain) break the Prime Directive? How many times did he shoot first and ask questions later? While he always worked for peace, sometimes the route to that peace was war or violence (e.g. Return of the Archons, A Taste of Armageddon, The Apple, Friday's Child, Patterns of Force, A Private Little War, to name a few). How do you explain General Order 24? That was a Roddenberry creation. Scotty also has very clear thoughts on this matter, "The best diplomat I know is a fully charged phaser bank!"
The bottom line is that, Roddenberry never preached pacifism or absolute morality. He did look to a future with a world better than the one today. But he stated that a better future and war were mutually exclusive concepts.
