If a group or government want to make a site off limits to diving I can respect that. You just have to tour the Arizona Memorial in Pearl Harbor to understand.
Otherwise I believe if the wrecks integrity is respected then diving them is fine. We also dove the wrecks of Chuuk and it was a great but sometimes a sobering experience. I hated seeing people taking bullets and spelling out their names, pilling up artifacts so they could get a better picture and even handling the remains of the sailors. As with the reefs these should be NO TOUCH zones.
