What does “no open borders” mean here? I’ve seen this term used but I don’t quite get it. Surely it can’t mean completely closing the borders? I.e. literally nobody can enter the country, ever.
Literally no tolerance? I always figured that like everything else, there’s a cost/benefit analysis to be done, and you try and tweak enforcement levels to the point where it gives decent results without costing the earth. No law is enforced with literally no tolerance in practice.
