Cameron directly referred to an increased threat from IS. Can you make an irrefutable case for that assertion?
Kindly tell me how Britons will be at greater risk from terrorism as a direct result of Brexit? Or how this country's population in 2030 will be exactly the same as it is 2016? Or why a British government free of Brussels' authority wouldn't choose to remove EU VAT requirements?
To name but three.
I apologise for answering your actual question.
With regards to your new question, I don't claim to know the mind of Cameron or IS leaders.
However the UK, thanks to slightly over half of its voters, has displayed to the world a rather ugly, far right leaning. Backing people like Farage and running campaigns on immigration with slogans and pictures like 'breaking point' aided by the the media's frankly disgusting campaign against immigration, and removed ourselves from the very institution set up to try and prevent European - and indeed global - conflict.
I think IS would draw quite a lot of encouragement and positive propoganda from those things. I think it might be seen as a victory to them which it sadly, probably is.
Might this translate to further attacks and increased support/activity, I don't think it would be preposterous or a lie to think so.
The points are moot really, politicians say what they have to and make predictions and forecasts, the leave camp have just relied on falsehoods so blatantly and with the kind of unashamed gall that has hallmarked the campaign.
Oddly people still swallow it and defend it more than the leave leaders themselves!!
