Well yes, it probably was, with very draconian immigration measures

You didn't put an actual figure on it surprise, surprise.

Your logic on this seems to revolve around the present and the past. Yes, we f***ed up in Iraq etc and yes, some of those Muslim radicals were born in Britain or Europe and that is a result of our first mistake to let their parents here in the first place. What we have to do and we failed to do before was get away from this short termism, short sighted approach and think about the future. How will allowing thousand upon thousand Muslims to come to Europe make things better? It will almost certainly spell disaster and plunge us into a near perpetual battle of ideologies where the only result will be more people being killed.
There can be no economic or practical argument to justify that.
If I were a cynic, which I am, I would almost suspect that the powerful elite who pull the strings are making this happen on purpose to help justify their plans for future incursions into Oil country. What better way to keep public opinion on side than to have citizen being blown up and shot by Muslims on their doorstep.

I didn't really fancy wading through death statistics in a year to determine a reasonable figure.

I think we need to be less political and more pragmatic in who we offer permanent asylum to, the old adage of 'Enemy of my Enemy' brought us a lot of Islamists in the 90s, who became a problem. I'm inclined towards being selective in terms of asylum towards civilians rather than militants, and especially militant leaders - and especially trying to restrict Islamists and fundamentalists. They'll have political objectives that are divisive to the UK.

I also think there is a nasty tendency with Asylum to then just dump people into British society, in poorer areas, and leave them to 'get on with it'. Personally I think that we have to take a more hands on approach towards integrating individuals into British Society - Similar to the post-WW2 program where refugees were effectively utilised to the benefit of the nation, and in return were given a small wage, training in languages and job skills and after a period of time of adjustment, were granted citizenship and allowed to move into society.

In the post WWII environment, this worked well. People were effectively 'forced into key skill areas' where there was shortage, and in return were fed, accommodated, their children educated and they themselves given necessary skills to function in UK society - and it worked well.

The current situation just puts greater strain onto the poorest areas of the UK, and really only ends up benefiting employers (cheap labour force) and low end landlords - and I also think its deliberate - It creates division among people, including the migrants, who probably have more issues in common, than opposition (i.e. blaming each other, rather than seeing the actions of the state and corporate entities that benefit from these decisions as a cause).

Ideally, I would suggest that we also could use refugees as a means of mobilisation of people from poorer areas with low employment into better areas of higher employment.

I'm inclined to agree with your cynicism, I think the threat is escalated and that there is a deliberate policy of using issues around fear of Islam to get involved in foreign domestic policy that is questionable in terms of UK security. Libya and Iraq are two good examples of that, but so is Syria, the UK were keen to get involved with the Rebels long before IS were on the scene, and I think that had a lot to do with Oil Resources.

You are Mr Spock. Do I get a prize?

Surely you'd just answer what you think the country wants to hear.
