There was no real indication for the scope and intensity of the hamas attacks. Based on US and Israeli Intel. There were some kind of warning signs, but nothing pointing to this ferocity. I think fighters got far further than they could dream of, and the severity of the response is a direct reaction to the failure of the isreali army to see and stop the attack. It’s difficult to believe that the kremlin had more and better information to know that an attack would lead to war on the scale we see today. And I’m willing to believe that Russia sees benefits in arming hamas through the lens of geopolitics, they aren’t controlling the actions of hamas in any meaningful way, I certainly don’t believe that.
Putin is just taking advantage and is absolutely never harmed by being seen as some kind of geopolitical mastermind. He isn’t.
