Ukraine's armed forces are slowly advancing and de-occupying the territories. The next two months could be decisive for the war.

Pawel Solokh, head of the Polish National Security Bureau, said this in an interview for Polsat News.

According to Solokh, Russia is using "carpet raid" tactics in the Donbass, but without high-precision weapons, its progress is disappointing for the Kremlin.

"Everyone is waiting for an offensive, because an offensive could create grounds for some kind of negotiations - either for peace or at least a cease-fire. Nothing of the sort is happening yet. All indications are that the next two months could be decisive," Solokh said.

According to the chief of the Polish Bureau of National Security, "crucial decisions" could happen in October. At the same time, he does not rule out that the Russian-Ukrainian war could drag on for a long time.

"Russia does not consistently refuse to conquer all of Ukraine, even if it takes years. It is somewhat reminiscent of the situation in the 18th century, when Tsarist Russia conquered first Ukraine and then the Crimean Khanate. It took years. I think this is the position of the Russian elite," Solokh expressed his opinion.

The Polish official also noted that in case of illegal annexation of the south of Ukraine, it increases the threat of using weapons of mass destruction, in particular nuclear weapons, against Ukraine.
