Skyscraper and food court will not be part of the memorial. No matter what gets built, there will still be a Burger King, a Brooks Brothers, a discount deparment store, a pizza place, and a hardware store directly across the street, and in full view of any visitors. Will those businesses offend your delicate sensibilities as well?
Building new skyscrapers there just sucks. Wanna build a hotel/resort at Pearl Harbor? I don't.
