Why you are simply being so evil letting the people die?
Any personal grudges?
They support nuclear technology from the evil russians. They are bent in establishing a shia crescent and wish the death of israel... then like the poster above said they breed like rabbits unable to apprehend a simple concept like water disponibility.
Are they really people? They want their theocracy, they must enjoy the fruits of it, to the end. Why shall I have mercy for people whose values and beliefs are opposite to mine?
The fun thing is that it's nice to see how are the allied of putinstan...

Why shall I have pity toward a revert to the mean? Barbarians.
ah yes, them evil russians and their evil plans. Well just as SimmonenY said, they'll probably start a war for it so we might see even more conflicts on the middle east with Israel.
And if you trap them I don't think they'll be just sitting around without doing anything.
