Is this a return to the idea of splendid isolation for Britain?

Now, for all EU countries (and more countries on the list they made public), you need to get a permit to enter the UK even for a vacation! And it costs £10 to apply for it. Some electronic online bulls... permit.

Seems to me annoying to say the least. Not sure what is behind this move. I hope that if they don't want certain people to enter the UK then they get some balls and announce blatantly in their faces the exclusion of those specific undesirable and unwelcome subjects. Not hide like cowards behind a blanket rule that affects everyone to curb their nausea and their headaches.

Sounds like it
No it is not
