"unwillingness on the part of Muslims in the West to provide moral leadership against Islamic extremism will ensure that the terror continues for a long time.""

Might this be because there are egregious examples of terrorism being exercised in what you refer to as "the West"? What do you think that the Muslim community thinks about drone warfare in Pakistan and Yemen? Or the destruction of Iraq?

As I see it, there is an unwillingness to provide moral leadership against Christian and Jewish extremism among those who practice those "faiths".

I don't condone Muslim terrorism or anyone else's but Islam doesn't have a corner on that market.
