Hi @velimir
Unfortunately, the borders of many modern states look like this. But when it comes to Europe, it looks sad.
But there is one BUT. First of all, when it comes to emigrants, this is fully justified. I've seen a lot of videos from my friends who work as truckers. There is a port in the UK where truckers come from different countries. (mainly for delivery and acceptance of goods). Near the port there is a camp of so-called "refugees". Unfortunately, the camp is full of men (the question is why do men flee the country at a time when women and children are staying there?). Behave these "refugees" very aggressively. They brake cars and cut tarpaulins on trailers. They attack truckers, they try to get on the trailer to steal cargo.
They are guests in Europe but behave as if they are masters. (and how many rapes in Europe?) It's disgusting.
All this I said about why they build fences from these "people".
But another thing is that politicians are building fences on the border with the allied states. Imposing people non-existent patriotism. This is wrong and here I agree with you.
All this is my personal opinion.
Good day
