As stated in the OP:
While religion contributes in many cases to increased feelings of loyalty toward a kindred community that may be oceans away from an individual’s country of citizenship, the primary cause of these horrible phenomena is foreign occupation.
Are the suicide bombings in Iraq primarily because there is a foreign occupation, or primarily because Saudis have a death wish (compared to Iraqis)?
Let's see the numbers of suicide attacks in Iraq, the numbers carried out by Saudis rather than Iraqis (and please show who is reporting or what the source of the nationalities of the suicide bombers are), and who they are targetting.
The attacks against Shia shrines etc are indeed +not+ because of the foreign occupation - I'll grant you this (I won't even argue that they are indirectly because of the occupation.. let's keep it simple).
Let's examine the proportions of attacks which are because of the occupation and those which aren't.
Over to you eh.
(Note that Pape's data set is more than just Iraq - but lets look at Iraq and suicide attacks there. I presume it is fair to say they started only after the invasion?)
Cheers,
Shafique
