One pissed off NYC Jihadist cab driver could take out every Watchtower office facing Columbia Heights with a car bomb. The Governing body have always struck me as paranoid. Underground tunnels, traveling companions etc.
The Watchtower slams the Catholics, why not Islam?
The Watchtower is afraid the Islamic religion would slaughter them, the Christian worldview has been able to take alot of crap, without going postal!. If the WTS thought the Muslims would tolerate Mohammed being called a fake religion (Look up ProphetofDoom.org), they would. Countries like Indonesia, Malayasia, Burma, and African countries would slaughter them. Muslims are angry when you try to hand them a Bible, the Fundamental mission workers in Turkey, were getting into trouble by handing out Bibles during their Earthquake mission disaster relief this year. How many JWs were sent to Turkey to help them, by rebuilding homes and kindling fires of love by good deeds? You don't screw with Islam, review the literature and you won't find much about Islamic views, other than their non-Trinity view of the deity.
As mentioned earlier and elsewhere...
because they are partners WITH Islam. They are similar enough to co-exist...split the world between them.
