Depends what you mean by petty in this context. They do have a reputation of vehicle thieves in many European countries, starting with Germany.
Reminds me of this picture.
Ehh, aside from Chechens and a handful of Ukrainians, they didn't exactly flee.
You're the one who knows shit. First of all, Polish government first talked about 500k refugees from Ukraine and at some point randomly doubled that number out of nowhere. Secondly, after the first time they bullshitted even about the 500k, it took Ukrainian ambassador around a day to call them out on their lies, citing official Polish numbers. Which, at the time, were whooping 2 Ukrainian refugees. For more keks, she talked about them at the end of 2015. Poland took zero refugees from Ukraine in 2015. Those 2 they took? They were from 2013. So from before war in Ukraine started, even though it's the background Poland uses for this horseshit lie. People like you make me sad.
Yeah, the presence of the few thousand Muslims EU wants to move to Poland would cause the cultural collapse of an almost completely homogeneous nation of near 40 millions Never mind the few thousand Muslims that are already there. Also, it's almost as if EU member states have specific obligations towards the EU or something. Funny how supranational law works. And don't count on Polish PM minister doing that. It'd exceed the foreign relations competences of the Polish government by far. Also, the prime minister acting on her own and not doing exactly what her party leader tells her to do is also implausible.
Sadly, Article 50 is meaningless here since EU can't initiate it for a country.
OK, where to start... Poland has 59 Ukrainian refugees, which is a pitiful number for a nation this large. Volhynian massacre victimhood doesn't give Poland bonus points for hosting Ukrainian refugees. Polish immigrants not going back is irrelevant. They don't have to so far. Their status is different. But they may have to depending on how Brexit unfolds. They are also a net benefit to UK and have one of the most positive numbers when it comes to reliance on welfare or abusing it. And Polish quality of life, or things like, I dunno, youth unemployment or disposable income, are rather sad when compared to western Europe.
Yeah, Poland is a pinnacle of stability right now. And dat democracy.
The only EU charter is the Charter of Fundamental Rights of the European Union which does talk about refugees:
Plenty of other EU legislation about refugees, migrants, obligations of the member states and penalties for member states that do not fulfill their obligations.Article 18
The right to asylum shall be guaranteed with due respect for the rules of the Geneva Convention of 28 July 1951 and the Protocol of 31 January 1967 relating to the status of refugees and in accordance with the Treaty on European Union and the Treaty on the Functioning of the European Union (hereinafter referred to as ‘the Treaties’).
Sadly, the EU actions didn't reach sanctions level yet. But Macron said he'll push for it if he wins French presidency, which he did, so there's hope. Maybe sanctions will actually make the Polish government rethink its actions. Or, more plausible option here, cause them to whine about foreign oppression and a threat to muh sovereignty some more.
