I suggest not.
If murdering random innocent people is supposed to make the West behave in a different way than it has thus far, then clearly it is not working.
I doubt that message will be received though.
When you are dealing with people who kill people because it enhances their unfounded belief in the superiority of themselves, their beliefs, and the notion that this is the way to convince people of their rightness, they don;t see that they are not causing an iota of change.
They simply think that their message is not getting through, and that's carte blanche to carry on hammering it home.
