Why Don't You Use the Power You Have?

Vlodomir zelenski is in effect asking the americans in the west to use it, saying, why don't you use it? You have to stop this man who is bombing his country.

I think it's understandable, from an american in european perspective, to be not too enthusiastic about that.
