The invasion of Russian drones into Polish airspace on the night of September 10 was an attempt to test NATO's response without provoking a full-scale response. This was stated in an interview with the British The Guardian in In Kyiv, Polish Foreign Minister Radoslaw Sikorski.
According to him, the UAVs were not packed with explosives, although there were all possibilities for this.
"Interestingly, they were all without explosives, which leads me to believe that Russia was trying to test us without starting a war," Sikorsky said.
Sikorski rejected suggestions that the Polish air defense was not ready for the invasion, as some drones flew hundreds of kilometers deep into the country and, according to reports, only three or four of about 19 were shot down, the newspaper writes.
As reported by EADaily, the purpose of the recent action with drones, in addition to the desire to test the ability of Poland and NATO to respond, could be pressure on the alliance. This was stated in an interview with the weekly Die Zeit by German political scientist Herfried Munkler, according to the Polish edition Dziennik.
