I read somewhere that the western wall is starting to decay in spots. They say it's normal wear and tear on the ancient limestone, but I wonder.......
When I was there, the Western/wailing wall certainly had holes in it. But I don't think they were more than several inches deep. Those are pretty big blocks of limestone.
However, no doubt, the Muslims would love to erode every hint of Jewishness they could--particularly from there.
Which has always been a mystery to me--except for their arrogance and greed . . . they claim Allah is generous etc. etc. . . . so . . . the Muzzies have Mecca and Medina . . . why not generously give the Jews Jerusalem--to be like their claims about Allah?
I guess they'd rather be clueless demonized blood-thirsty idiots rebelling against the God of Abraham, Isaac and Jacob at the urgings of their demonized leader of eons ago.
