Even Russia has shown itself to be more of a minnow than we thought…

Russia is currently stalemated in a limited war against a substantial (but similarly limited) chunk of the NATO arsenal. As a point of comparison, in the last 20 years the U.S. has lost two wars against non-state actors where it used everything but nukes.

The U.S. hasn't fought a war like the Russian-Ukranian War since Vietnam or Korea, and the results there weren't a lot better than what Russia is seeing now (despite the U.S. doing far more indiscriminate strategic bombing).
