From the Gettysburg Address:\
"But in a larger sense, we cannot dedicate, we cannot consecrate,
we cannot hallow this ground. The brave men, living and dead who struggled here have consecrated it far above our poor power to add or detract."
If Lincoln said that he and his government were incapable of hallowing Gettysburg, then I don't think that Obama or Bush, or anyone can "hallow" Ground Zero. Or even the Pentagon. Strange that we are not hearing about the PENTAGON being hallowed. Hell it even has its own mosque, right inside the Pentagon, Muslims are praying to Allah RIGHT NOW only inches away from where brave US servicemen died.
Of course, Gettysburg was designated a National Monument or Battlefield, which is as close as a sectarian government can come to making a site "holy".
I do not believe that Obama or any president has the ability to "hallow" anything. I can't see how anyone can believe that he could.
The soldiers at Gettysburg died for a cause. The people at the WTC (and at the Pentagon and in that plane) were just bloody unlucky.
How about the victims of the Sultana? should we call that place in the Mississippi where its boilers blew up "hallowed" as well?
