If you buy a drone for lets say 1000$ from Xiaomi via AliBaba, 100$ of those go to AliBaba maybe 1$ goes to Russia. from the 900$ left for Xiaomi, 600 are gone for the production. 300 left, 3 go to Russia. 4$ for Russia. But if this drone helps invalidate only one russian soldier, that 4$ are easily worth 100000$. If it helps invalidate a tank, it goes to the millions. Thats easily worth it if there is no alternative
