Do we need that on top of Ground Zero?
Cross two streets from the mosque and you will be right at the World Trade Center site. If you crossed the street from the mosque, walked through the front and back doors of the buildings across from the mosque, then crossed the second street and walked through the front and back doors of those buildings, you will be right at the World Trade Center.
The new World Trade Center will be a very tall building that will loom over all of the other buildings around it so when the muslims are looking out the window of their mosque, they will actually be looking right at the World Trade Center up close. The World Trade Center will be right in their faces.
