Just as the Shinbet ignored their operatives warnings about the incoming 7th of October Hamas attacks, the FSB ignored the US warnings about this terrorist attack. My opinion is that this worked for Russia as intended. Russia was just looking for its very own 7th of October moment that they could stroke in the media to garner more support from the population, including from regime critical parts of the population. The moment the attack happened the Putin propaganda machine started pouring with “Ukraine did it” and not even two days later Ukraine is pummeled by one of the biggest rocket barrages since the start of the war, the biggest tank assault launched by Russia, and a new conscription law is signed to throw even more meat at the wall.
