Didnt the Taliban propose that a couple decades ago?
The Islamofascists have demanded this several times in recent years. One of the medieval caliphs actually tried to tear down the Menkaure pyramid, smallest of the big Giza pyramids. The damage is visible. But the amount of labor and time required to finish the job (particularly since the Great Pyramid is more massive than the other two put together) made the moron call off the demolition.
