There's enough tragedy and heroism in life without war. As any inspection of the DT confirms.

The main significance of war in most songs isn't the big stuff, the battles - it's the lovers' partings and the bereavements that result, in the margins of history.

If we ever get things sorted out so as not to have wars every few years (well, actually more ot less conbtinuusly somewhere or other), life's still going to be pretty rough at times. Even if we get a juster society, it's never going to be an easy ride through life.
