The question is - what is happening that these same terrorist that were educated in Madrasas paid for Saudi money, do not attack Saudi trains? 

They have a religious logical basis for doing so.

What logical basis?

It is the evidence that the princes of the House of Saud live utterly indulgent lives in which they whore with white women and booze whiskey and vodka with them; and some have a delight for bacon. 

This is enough to merit DEATH in accord with the Law of Sharia that the Saudi princes officially are such premier and ardent defenders of.
