I think its a good song. Maybe not the best on the album but its very fitting and the idea is also fitting.
There is a great deal to be said for the idea of people (politicians) fighting wars with the realization that they are never actually coming into the true line of fire. It enables them to arbitrarily use phrases such as "evil doers" and "infidels" to justify war without coming face to face with the realities of war and self sacrifice.
The military may not be a very enjoyable career but it is certainly an admirable one. Unfortunately 'the powers that be' use extreem dedication and dicipline to their advantage in staging wars for purposes of power, status, sex and glory (and sometimes arguably religion).
