Hm..... certainly trueWell, no, you can actually.
It's called blocking the entrance and saying, to paraphrase Australian s**tposters on the internet:
"F**k off, we're full."
Not the nicest thing to do but well within a nation's rights. Maybe enough countries saying no will teach them to stay and stand their ground for once.
In fact, it's been quite interesting watching the various differences in what happened when Ukraine went to hell and what happened when Afghanistan went to hell.
But for such ppl to stand their ground means directly clashing with Western interests
You see Iam not dumb, if the EU or the USA really wanna get rid of the refugee issue once and for all, then maybe stop supporting the corrupt leaders that make their lives miserable.... Period! However, the West will never do that as they need such corrupt ppl in power to ensure that they can continue squandering resources and ensuring that their hegemony remains stable
After all, most of the world's riches is located in the Middle East and Africa; yet, most of the poorest nations are present within these areas..... see the link? This is life after all
