"You see, Paco, there are those with guns, and those who dig".
did Ukraine have actual control and the ability to deploy them? did they ever have the launch codes? unless they have the ability to maintain them and to light them off, they are nothing but expensive status symbols.
I doubt the Ukrainians have the resources to develop their own from scratch, but could be wrong.
The way to deal with the Russians is to develop technology that kills the price of energy.
