Can the U.S. punish Russia in any way if it chooses to fire artillery shells at Ukraine for the next 10 years?

Mersheimer predicted that Russia will seek to destroy Ukraine. I am wondering since this is likely the outcome if the United States can do anything against Russia without escalating the conflict. They already emitted a lot of sanctions, I don't think they can do anything; otherwise, Mersheimer would have said something about it.
