Do not underestimate Russia. Those fuckers are strong. According to my gut, they're building factories that produce drones better than what Ukraine has. It isn't like Ukraine can hide their developments, Russia has easy access to space. They also openly modify the weather and no doubt can control the weather remotely like the US. This is Drone War 1. Unless Russian leadership is genuinely retarded, Ukraine cannot win. Russia can build more factories and therefore, more drones. Russia will likely flood Ukrainian air with drones and force the skies to rain for weeks on end so the new Ukrainian laser defenses dont work, forcing them to use up their dwindling munitions. Or they will simply nuke them. The west would not react.
