Well, we're certainly not a nation above God, across God, after God, along God, around God, in between Gods, through God, aboard God, and most *definitely* not about God, so I think you can just let it ride. The phrase was designed to show our relationship to God with Him as the object, not as the subject. We're not "telling God" to do anything... unless, of course, He wants to put us above Himself, which is not within the nature of any God.
The question here is not what God has to say about America, but what we have to say about Him.
And the response by many here is "nothing," because they don't believe there is a God. The problem then becomes how to take God out of it without really screwing up the pledge.
And it's not that difficult, and frankly, I don't care. Most of the time when people say the words "under God," they're not really even thinking about God. I as a Christian don't want people thinking about God in a half-brainwashed state, so I'm fine if y'all want to take it out. Doesn't bother me any. I don't think it's that big of an issue. It's not like God's going to cease to exist just because people separate loyalty to country from loyalty to God. Which I advocate.
