I bet none of the Western leaders are "believers"!
How can - for example -a millionaire like Cameron be a follower of word of God ( as presented in the Bible).
No, all those people are far too intelligent to believe in that nonsense!
But A) They wouldn't get in power if they declared themselves atheist
and B) It suits their agenda to have a great many of their citizens believing in the next world, the power of prayer and, rendering to Caesar that which is Caesar's!
