Boots on the ground are inevitable, it's just a question of whose. I know it's the fashion for people to want to do stuff remotely but someone is going to have to intervene in the manner that the UN and NATO should have done in Srebrenica 20 years ago.
Sadly we're also going to have to be a lot more diligent in identifying those who'd seek to do us harm and economic migrants. Given the circumstances, if I were a refugee feeling a war zone (as opposed to a migrant seeking a better life or a budding terrorist) I'd understand and accept why measures such as these would have to be taken by those tasked with the job of helping me and my loved ones.
I'm still waiting for confirmation that any of the celebrity great and good who jumped on the holier than thou bandwagon and promised to take in refugees have actually kept their word and helped anyone. They seem to have gone the same way as Euro proponents but maybe they're all just keeping their humanitarian works a secret so as not to embarrass the rest of us...
