So presumably we leave these poor people to the horrors of IS and wash our hands of it! Ok we don't sell arms, but for certain someone else will! Of course we could then pat ourselves on our backs, and congratulate ourselves on the moral high ground that we would then occupy in the vain hope that other countries will follow suit, which I'm sure will be an enormous comfort to the people on the ground. Imo all we can do for the time being, is live in the world as it is, and hope and pray for better things, somewhere, somehow, but don't expect too much too soon, to avoid disappointment.
