Rorty: well said, I think it unlikely anyone is basing a wish to leave just on attacks in Cologne, Austria and Sweden.
However , Germany's open invitation demonstrated clearly that our government doesn't have self determination.
UK say that we will take refugees from camps in region deemed to be most at risk. However, Germany issue a 'Hunger Games' style invitation of inviting the strongest and fittest: if you can physically make your way here and don't perish on the way, you win the right to become an EU citizen.
Ultimately those people will have access to Britain once an EU citizen, demonstrating our Governmemt stating a wish to accept a certain level, is ultimately a futile exercise. Yes, of course the answer to that is that they will be EU citizens at that stage etc, as I know some will say, but the point is a country's own quota on refugees is ultimately not in their control.
Our government may as well be talking into the wind,
