– Indeed, this is certainly Russia's attack on Poland, though for now, a warning one. I believe there could be two direct causes. Firstly, this improvement in Polish-American relations, which is certainly not welcomed there, and a warning to Americans that they will have trouble here – stated Jarosław Kaczyński in an interview with Radio Wnet.

– And secondly, the blocking of the border, because that is a significant blow to Belarus, but also to Russia, and partly to China. And I believe that's a response to that, but perhaps especially that first reason may lay the groundwork for such reasoning, that this kind of matters, perhaps even in an intensified form, will simply repeat themselves – continued the PiS chairman.
