He said this during a briefing with Finnish President Alexander Stubb in Kyiv.Zelenskyy said that the incursion of Russian drones into Poland through the territory of Ukraine and Belarus was definitely not a coincidence, and he shared his assumptions about the goals Moscow was trying to achieve with such actions.He also drew parallels between this provocation and the way Russia’s occupation of Crimea started in 2014."In my opinion, the scariest part is that this attack resembles Crimea. Psychologically — how is it different? Now it’s technological warfare, you don’t need men in uniforms, the 'green men' who entered your territory. Today, Russian-made drones have played that same role on Polish territory," the president said."The most dangerous thing is when someone — the U.S., as happened with Crimea, or other partners — sends signals that ‘the main thing is not to escalate into war.’ So to me, this looks very much like Crimea, and I believe this resembles a ‘rehearsal.’ Putin’s messages are in the media, they are public, they have always been there — about certain parts of Poland that the Soviet Union at one time ‘gifted’ to Poland. So the rhetoric is the same," Zelenskyy noted.Russian drones in Polish airspace: What we knowThe Operational Command of the Polish Armed Forces placed air defense and aviation units on high alert following Russia’s night attack on Ukraine on September 10, during which Russian drones entered Polish airspace.
