Willy McBride points out the stupidity of war.

The songs makes that assumption for sure; for Pte. W. McBride (and millions like him down the aeons of human history fighting to defend heath & home) it wasn't stupid in the slightest. This is why I hate the song & its sentiments, because it assumes a position of idealistic moral correctness which has nothing to do with the real world in which war is a grim necessity to which we owe our present freedoms.
