If our government is too paralyzed to help fund their defense, there are ways to bypass that.
A lot of the pro-Ukrainian youtube celebrities, guys like Artur Rehi, organize nonprofit fundraisers to buy necessary military equipment for them, and then dude goes and drives it there himself from his home in Estonia. And videos the whole thing and publishes it on his youtube, so people can see what their donations bought. Transparently.
What they need most is drones capable of carrying a weaponized payload, and those don’t require a full-on military-industrial complex to supply. A person can just buy 50 from normal commercial suppliers and send them, and that is very directly helpful assistance.
We may need Uncle Sam to help out with the Bradleys and F-16s and such, but so much of this war has been and continues to be waged by light infantry using whatever they can get their hands on.
