Larry summarizes it well.
In my opinion, none of these attacks could have been planned and executed without assistance, if not the direct involvement, of Western intelligence and NATO officers. The drones likely were activated by a remote signal made possible by Western satellites and/or systems like Starlink. Those systems also played a critical role in enabling the drones to navigate to the targeted airfields.
While this is clearly a PR victory for Ukraine, it is a classic example of a Pyrrhic victory–i.e., a tactical win, leading to a strategic defeat. The Trump administration is denying any knowledge of the attack. I take that disavowal with a big grain of salt. People within the CIA and USEUCOM offices, who are providing assistance to Ukraine, likely knew about the plan, and may even have provided intelligence support to get the drones to their targets. Like any covert operation, they may have tried to give Trump plausible deniability, but the Russians know how this game is played.
I expect Russia will launch a massive retaliatory strike after the talks in Istanbul on Monday conclude. The Ukrainian attacks on the bridges, the train and the airfields have done nothing to alter the situation all along the line of contact in Ukraine. News continues to pour in from the front, from both Ukrainian and Russian news outlets, painting a picture of growing desperation, even panic, among Ukrainian forces, as Russians capture more territory and kill more Ukrainian troops.
As I posted in the previous thread--I only now recognized that I don't know math and warfare. 3 TU-95 MC and 2 TU-22M3 destroyed AND damaged (meaning some of them will return to service) is roughly (among active, there are more in reserve) 70 heavy + 90 middle =160 bomber aircraft: so 5/160= 3.125%. That's it, Russia lost the war. Tomorrow Russian delegation will accept 404 and EU's "conditions" and that will be it.
