I think perhaps a more interesting question is, "Is there any room in Christian theology for assassination for political/economic reasons?"
Many a Pope had people assasinated for just such reasons. Is there any room in Christian theology for war?

so much as questioning how those identifying with Christian dogma can support a Jihadist like Roberts
I saw nothing from him that says he wants Chavez killed for religous reasons. In this case his relgion has nothing to do with it.

Let me add this. I would prefer that national leaders be assasinated over war. The politicains start the wars let them be the ones who die for their ideals.
