It's the old quick blame someone else so we don't get found out trick, blaming easy targets such as immigrants and the EU because it diverts people to their view even if it completely wrong so people don't cotton on to the fact that they are the problem.
That's why BoJo used the "Get Brexit Done" because it was something he could use to try and lay the blame for all our problems at everyone else whilst hiding the fact that all of the mess we are in is down to the conservatives.
Unfortunately people lapped it up and are going to feel the pain because of it.
I think that goes to show just how reactionary and selfish the baby boomer generation is and always has been.
Yes the ones born just after the war who didn't experience real suffering. Ask most people who were alive during the war and you'll find that they are ashamed of what Britain is becoming, esp. when so many innocent people died so that we could get rid of fascism only for it to come back again.
The world works better when we all work together for the greater good, isolationism only creates divides and anger.
