Subjecting innocent people to this kind of sonic torture seems to go hand in hand with the Israelis general policy of seeking retribution against civilians and combatants in response to the homocide/suicide bombings of Palestinian terrorists. Interesting case of selective attention you provide: is it not the Palestinians who stormed the Church? Is it not they who occupied only the Armenian and Greek Orhthodox parts, calculating and manipulating Vatican?
And, by what measures do you judge this operation? DO you want the Israelies to do what we did 20 years ago: allow the standoff, which may last for years (unlike the Arabs, they will NOT offend Christians by storming the church)?
Interesting standards you apply, especially considering your screen name. "Curiouser and curiouser," said Alice.
The main body of the Church of the Nativity is shared by Armenians, Greek Orthodox, and Catholics. The nave, altar and grotto of the Church is under the shared supervision of the Orthodox and the Armenians. The adjoining Church of St. Catherine is under the direct supervision of the Franciscans. There is complex arrangment by which these various Christian groups share the sacred site of Christ's birth. The Franciscans and the Greek Orthodox have made it clear that if it had been Israelis rushiing into the Church for sanctuary from an overwhelming Palestinian army outside, they would have done the same and remained to protect the Church and given sanctuary to those who sought it.
The use of a sonic weapon is invasion of the Church as much as if they had filled the Church with tear gas -- which is strictly forbidden under the accord with the Vatican.
