Most of Obama's words thus far suggest that he is staking a claim for the Moral High Ground. He has released the torture memos because he believes he is better than the Bush administration in this regard. He is releasing the pictures of "torture" prisoners for the very same reasons. When he was oversea he apologized for past US actions, because he nominally believe the US could have done better, and that under him we will. There are two things to consider here.
First is that if he thinks this will make the US safer or better he is wrong. Those who work toward our destruction do so not because of some reasoning, but some hatred. That we could have been better angers them. That we believe we could be better also angers them. There mere fact that we are different from what they want to be angers them, regardless of how good we are. Staking claim to the Moral High Ground may make things worse for us. It certainly not keeps us safer. Those that seek to compete against us will not treat us better, or help us further our goals. They compete against us because they think they can beat us. Given any opportunity to do so they will certainly try regardless of who has the Moral High Ground.
Second is that if he thinks he can claim the Moral High Ground he is also wrong. This sort of thinking seems rampant to those without practical experience in life, living by concepts they believe the world should operate by rather than the principles the world lives by. This is akin to a rich couple believing their wealth keeps their estate well maintained, rather than understanding that it is still the housekeepers and gardeners' labors over dirt. Or a hospital CEO proclaiming how many lives his hospital saves, without acknowledging it is the doctors and nurses work in soilage and pus. Or a general believing he won the battle rather than the soldiers killing and maiming. The difference between Obama's Moral High Ground and reality is the difference between Ideals and Practice.
At best, his stake for the Moral High Ground only shows his naïveté. What it clearly reveals is his hubris, not his humanity. And through it all, he has also demonstrated willingness to use politics to further himself.
