There are wars to protect the innocent and to free the oppressed ("de oppresso liber") where such a prayer is justified:
"O Lord our God,
help us to tear their soldiers to bloody shreds with our shells;
help us to cover their smiling fields with the pale forms of their patriot dead;
help us to drown the thunder of the guns with the shrieks of their wounded, writhing in pain;
help us to lay waste their humble homes with a hurricane of fire;
help us to wring the hearts of their unoffending widows with unavailing grief;
help us to turn them out roofless with little children to wander unfriended the wastes of their desolated land in rags and hunger and thirst,
sports of the sun flames of summer and the icy winds of winter,
broken in spirit,
worn with travail,
imploring Thee for the refuge of the grave and denied it –
for our sakes who adore Thee, Lord,
blast their hopes,
blight their lives,
protract their bitter pilgrimage,
make heavy their steps,
water their way with their tears,
stain the white snow with the blood of their wounded feet!
We ask it, in the spirit of love,
of Him Who is the Source of Love, and Who is the ever-faithful refuge and friend of all that are sore beset and seek His aid with humble and contrite hearts.
Amen."
If this is not justified, then you have no business going to war.
I would like to see the US Constitution amended such that any member of Congress who votes to declare war (or to deploy our military overseas for any reason) must recite this prayer.
