Morality can be practical on the battlefield. Battlefield performance is a function of discipline, teamwork, initiative, motivation and other personal characteristics as well as training and weapons. Trust and faith and honesty are invaluable in promoting individual and group confidence. While fear has been shown to be a more consistent motivator than love, love is the more powerful motivator. Sacrifice for one's teammates, one's unit, and one's country comes easier when driven by love, trust, faith, and honesty.
Willing employees are more productive than slaves.
God as a source of personal and national power is a very old concept that is very much alive today. It is amusing to my cynical mindset that Al Gore, perhaps as the result of focus groups and polling data, is trying to seize the initiative with respect to God from the Republicans for political purposes. The American public seems to be turning to religion in times of the moral crises represented by school shootings, ethnic cleansing, genocide, a general lack of civility and decline in public education. The Democrats seek to jump on the religious bandwagon and portray themselves as an alternative to an extreme right wing group of intolerant and rabid Christians. Perhaps I am reading the tea leaves wrong or my cynicism has overrun my compassion.
