I think anyone spouting the old, with God on our side excuse for war may do well to look not at the war, but the aftermath. After WWI the resulting punishment of Germany gave rise to Nazism, after WWII, we built INTERPOL NASA and a host of other institutions around Nazi colberation and lauched 50 years of unrelenting war to establish totalitarian capitolism, a system where greed is good, where morality is based on profit, where the poor are used to make consumer junk which it is patriotic to buy... need I remind folks that the Civil war did not end slavery, but only launched us into one hundred years of Jim Crow? And any one who thinks slavery ended in the US should ask our prison population of over a million, many of whom are doing unpaid work - scabbing on Union workers... I don't know, doesn't sound like God's work to me.
