Well, Frontex, the EU border patrol agency, was imvolved in illegal pushbacks (you cannot deny entry to asylum seekers, not speak of the duty to help people in dostres at sea) multiple times. Even resulting in the death of people. Nothing happened, besides having the head of Frontex being removed. Go figure.
That is certainly a.... take on Frontex job. But by that take, tze job of border police is to shoot at people. Well, at least in East Germany that was part of the job description, they aimed at people tryingbto leave so.
And invaders require an invasion. That means war, and then it woupd be the various NATO navies and airforces doing the shooting.
What Frontex does is just simply illegal and inhumane in some cases.
No, they are actually forbidden from doing that. They should stop illegal migrants, that is a different action and different people. To stop invaders we have an army.
They are just a symptom of what happens when you give people power and no accountability.
