On top of that, the success of these strikes proves that Russia's air defense systems aren't anywhere near as effective as once advertised. The fact that a 50-year-old jet-powered Soviet drone was able to travel literally hundreds of kilometers into Russia suggest that these systems, or at least the ones deployed in Russia, aren't as effective as the Kremlin thinks they are, and that is obviously bad news for Russia because it leaves Russian targets vulnerable to Ukrainian drone strikes, but it also undermines their nuclear deterrent too. That's because the strength of any nuclear deterrent depends on air defense because you need good air defense to guarantee second strike capability and protect against a retaliatory strike. Now obviously, if Russia's air defense isn't as good as portrayed, then it undermines their nuclear deterrence because other nuclear powers would know that they'd be guaranteed to strike their targets in the event of a nuclear exchange.
Sure, a low flying drone is on par with an ICMB. There's plenty of shots of Anti Air taking out not only drones, but multiple HIMAR missiles also, which travel at supersonic speeds, unlike a drone.
The hilarious fabrications only work on the ignorant and moronic alike, people who recognize the discrepancies in your propaganda will undoubtedly roll their eyes or turn away from such blatant falsities.
