I suppose it was ok to destroy millennia old Buddhist statues in Afghanistan, countless holy places in India, and even underneath the Temple Mount. We saw when Palestinians desecrated the Church of The Nativity in Jerusalem by using it as a base for snipers and desecrating the insides while doing so. No big deal. After all, it is a holy site of infidels, not a cartoon of Mohammed. Why waste a good rampage on infidels?
Like Communism banning music and religion, or Nazi book burning, Islam has a way of trying to create its own past and future. The entire world outside of Islam knows that there were Jewish temples on that site. Ancient Babylonian and Roman references to them exist, as well as the actual artifacts beneath the old Temple site. The same artifacts Arafat tried to destroy. Now the Muslims have concocted a story that those Israelis who are unearthing Jewish and Roman artifacts of the time the last temple stood, are plotting to sink the Dome of The Rock. Why would they do this? Because in the huge piles of rubble left by desecrating Palestinians, the Israelis have unearthed more proof that they existed there long before the Palestinians.
