John, I think I'm right in saying that Daesh don't get a say, they aren't part of the UN and they aren't a legitimate State. What is important is that the countries in the region get their act together and as part of the UN play their part in securing a peaceful solution. The reason I believe the UN hasn't acted is because their are too many vested interests in the arms trade and I've posted before a table showing just how profitable the war in Syria has been to countries likes the US, Europe including the UK and Saudi.
Some people believe that the borders in the region may not remain as we know them now. That may be the sort of concession that might come from a negotiated settlement.
Kevin, just how did we get into a situation where there is mass migration into Europe from Afghanistan, Iraq, Syria, Lybia (that used to be the end point for most African refugees) in the first place? As someone else said recently we reap what we sow!
And by the way, that country so dear to many of our hearts has a lot to answer for but the promised international aid to keep refugees in Jordan, Lebanon and Turkey was not forthcoming and is another one of the reasons why the numbers of refugees coming into Europe has recently spiked. And it's going to get much worse the way things are going.
