The end result is total demographic change, which they appear to want. The UK will cease to exist in any meaningful way. We've seen what the islamists do to historic monuments, libraries, places of learning. They have no regard for the environment, wildlife or sites of special scientific interest. This will get a lot worse.
I wonder if, at some point, the security services will just be instructed not to look for, or foil, any further islamist plots. The Soviets knew what it felt like to fear their governments. I wonder how long the government can keep pretending they represent us for. The Fabian logo is literally a wolf in sheep's clothing.
