Um, I really hate to point out the obvious, but -- hellooo? -- a "mosque" on the "Temple Mount"?
We have all figured out, by now, that these 7th century holdovers aren't the shar, er, uh, they're not the brightest bulbs in the marquee. So, that oughta explain why they went and put a mosque on the Temple Mount, in spite of the fact that EVERYONE (except them, obviously) knew perfectly well that a "Temple Mount" is for [drumroll] A TEMPLE.
Seeing the truth in 20/20 hindsight has really gotta hurt, so it's no wonder they're so danged testy about their centuries-old boo-boo.
