Maybe in his mind but like the USA there are far too many left wing brain washed in Britain
The attack near Westminster, the blowing up of little girls, and now this is causing many to stop listening to the “stay calm, carry on” message that they keep getting from the politicians. They know it’s just going to keep happening and vigils, calls for unity, etc., will do nothing.
Even some of my liberal UK family members seem to be changing tone. They won’t call out “Islam” as such, but they’re using language like “too much immigration, we can’t take in everyone”. Remember, this is a country with “hate speech” laws that are used if you publicly speak out against Islam. So people seem to talk like this so they don’t get into trouble.
There’s a recognition that there’s thousands of terrorists and the system can’t handle it.
You’re probably right that there’s not yet critical mass but I don’t think it is far off.
