I have seen similar things happen before multiple times. One I can remember: https://www.bbc.co.uk/news/world-us-canada-42358227
So you think anyone with enough determination ...
Also I am going to remind you we are talking about a twenty two year old girl who went to a fucking war zone knowing that she will be apprehended by soldiers of a fascist regime. I don't know the last I saw a twenty two year old girl do this. So yea I think this situation is more unique than you elude to by your three dots.
Given that you asked such a loaded question, you at least must have some speculations as to why she was able to speak to the EU?
