How could we analyse James Blunt's song "No Bravery?" What might be the themes and song-writing techniques used in it?

It is clear that this
song is designed to evoke the horrors of war by shocking the listeners into imagining the
pictures he sings about. Note too how the lyrics cut through popular impressions of war and
soldiers - there is now "no bravery", only "sadness". Apparently the war has
been so horrific that there is no room for thoughts of bravery or considerations of honour -
only sadness is the repeated refrain, emphasising the terror of war and the human cost. The
message seems to be let us learn from this horrendous chapter of human's history and let us not
repeat it.
