This is a lie, please stop spreading those. There are no "all barbed wire" borders, no anti-personnel mines, "guards with automatic weapons" sounds like some meme from 80s video games (which border guards anywhere in the world don't have some rifle with automatic fire mode?). Young people from Ukraine can currently travel free as far as I know.

You were thinking about russia, weren't you. Its not true even for that shithole, but much closer.

I work with plenty of people from Ukraine. And recently, someone went abroad. So it's definitely still possible.
