I suspect that as the Middle East continues to become more unstable, the Ark of the Covenant, the Tomb of Jesus and the Temple Treasury will all suddenly re-appear.
After the location of John the Baptist's Cave was announced, we heard that searchers were close to locating the Temple Treasury. I'm waiting for somebody to claim they've located the Ark and the treasury.
Actually, I've long thought that the WOT will ultimately bring MORE stability to the ME. And, if conservatives achieve some of their long-term goals in drilling domestically and the result of that is less dependance on foreign oil, the ME countries may have to find alternative sources of western dollars.
Working for a revived fascination for biblical sites and our historical Judeo-Christian heritage would be to the benefit of the ME countries. A surge in tourism would provide new jobs and revenue in the ME. Yes, and along with this will be a plethora of fakes and forgeries.
As to cui bono, there is great profit to be made from such antiquities. That said, I don't think the various Christian Churches would find them valuable. Having faith requires a heck of lot more than a relic.
