It's true that the refugees can't expect other nations to just accept them. It would have been right for Europe not to take them in. Perhaps I'm looking at this from a humanistic point of view. Like say, if we were to make the decision. It was obvious to Europe, these governments aren't stupid, that taking these refugees in, means accepting the risk. And this is the result of it. However, would it have made them feel 'right' if they did the opposite, and now watching the death of these refugees in their own countries, by their own people, knowing that they could've have helped in some way.
I think the people who made the decision to take these refugees in, faced the same dilemma:
Take them in and accept the risk.
Let them be and live the regret.
Either way would have been morally wrong, and morally right. It's the humanistic values (can't say Christian values, because this wasn't a decision made by Christians officials alone) that got the better of them, the 'greater good' or the 'human cause' whatever it is they call it. But this is the price they have to pay.
If the decision was mine, I would have probably done the same, and took them in. Which is why I'm not a government official, cause I wouldn't have made a difference. If there was a strategic way to handle this, a win-win situation, I probably have my blinders on, because I can't see that.
