Imagine a psychopath has broken into your house and is attacking your family. You call the authorities and everyone in between to protect you, nobody listens, you call your friends to come help but they're busy and have to think about it. Nobody is coming and this psycho keeps killing your kids. Better grab the gun. Suddenly all your friends are like "don't do it! Guns bad!"
United States has almost single handily help Ukraine with guns and artillery and for what i've seen in west media, nobody is directly against Ukraine defending its territory, the point of recurring to nuclear weapons is absolutely insane considering that anything that touches those bombs becomes a wasteland, and if that happens, what's stopping russia of doing the same thing.
Russia is no good and Ukraine is not a lady in distress, more like a toy to pump blood money and make war lords and their clients more rich, going nuclear wont profit anyone, "the fun is over".
Regardless of who provides the slingshots, someone has got to know how to use them.
Still, even with foreign support, Ukraine has singlehandedly revolutionized drone warfare. That is awesome and extremely frightening at the same time. The Switchblade was neat, but it supposedly costs $52k. Ukraine is strapping RPGs to drones for what? About $1k?
