History is constantly rewritten and updated. History from my days has been altered or changed to suit our PERCEPTION of what really happened. We deny the fact that if Hitler had oil, we would all be speaking German. We paint and 'doll up' history to suit our cause.
Regardless of when 'GOD' was added to anything is a way to appease a certain majority, and that majority is that those who BELIEVE in God far outnumber those who don't. The joke is that people in the USA believe it is a "Christian" God, whereas it might be a Jewish god or a Muslim god or a Hindu god or a Buddah god or a mother nature god or a Satanic god or an Atheist god-they believe there is no god, therefore their BELIEF is that there is no god.
So you see, God refers to a government that knows what's best for you. The whole Pledge should be trashed in my opinion. Nobody pledges allegiance to any flag anymore. So why do you put it UNDER GOD?
At one time people were arrested for desecrating the flag...ask the Rolling Stones, but Brian Jones is dead. Now it pretty much is your Constitutional right to even defecate on the flag.
Now you see why separation of church and state are a must...but don't give Jesus credit for that one!!!
