This is a pretty tricky subject, isn't it? On the one hand, it could be argued that conscription, and/or the draft, is necessary to protect us in situations like WWII. On the other hand, it could be argued that when governments have conscription and/or the draft available as an option, it becomes much easier for them to wage war for reasons that may not be very legitimate.

I don't have any answers except that I think it's necessary for there to always be a conscientious objector option available so that if individuals believe that a war is being waged for reasons that are not legitimate, they have a way to follow their conscience, just as those whose consciences tell them to fight have that option available to them.
