AfD Party is growing ever more powerful throughout country [187]
How would that be in Poland's interest... let's see...
Millions of Ukrainian refugees would travel to Poland (and not allowed into Germany ofc)
Poland is in the state of demographic collapse; millions of white, Slavic Christians would be a blessing.
Poland has also now a long border from Kaliningrad to Lwiv with Russia and its' proxies.
Poland's border with Ukraine is shorter than our border with Slovakia, so it wouldn't extend the border that much. Besides, neo-banderist Ukraine where Waffen-SS units and UPA genocide perpetrators are still celebrated as heroes is not necessarily a friendly country. The collapse of Ukraine, or more likely the creation of a smaller and weaker Ukraine, would not necessarily be bad for Poland.
supporting Poland/Eastern Europe would become next to impossible without Germany
As far as I know there have been some voices of criticism of NATO from AfD politicians but, as a national party, it has not adopted a formal policy of leaving NATO and I don't think they ever will (Russia is too unpredictable, as we have seen, for them to risk such move).
