Why try to stop them from going over there? Wouldn't it be better to have those ISIS sympathizers over there where they are more likely to be taken "care" of rather than here plotting mayhem?
Indeed. Viewed from a pesticide perspective, let ISIS be the ‘catch crop’ that draws the pests that would otherwise destroy your main harvest.
I find it amusing ME leaders are alarmed about IS: they have no control over them with which to manipulate world politics and oil prices.
