Is the goal of such a policy to expose our leaders to the horrors of war, and hopefully yield a more compassionate government? A noble idea, but to implement it, you would basically need to actively pursue a state of war. If the government of enlightened former-warriors created a world without war, would that be a failure for future generations because their leaders wouldn't get the exposure required? At the end of the day, we ought to find more sustainable ways to prepare our civil servants and filter for capable leaders.
