Whether the Ark of the Covenant goes ZAP as you say, I don't know. Christians believe in a new Covenant established by the Founder of Christianity. The Old Covenant, although holy and highly revered in its time, has been superseded by the New.
This concept is the basis of the animosity of Jews for the early Christians. Yet, for the sake of the Jews, I hope that they'll find a remnant of this most important image in their history and that it will not fall in the sacrilegious hands of the Muslim.
Actually, the new covenant fufilled the old covenant. God does not change his mind. Do not forget that the names on the foundations stones of the new jerusalem are all jewish names, and the gates are named after the 12 tribes.
You become part of the family by adoption, you do not replace it...
If the Muslims find the Ark, and they are able, they will destroy it, if they're able. It's part of their faith to destroy all other religions. The US press won't run photos, but they use headstones from other cultures as paving stones.
