Okay, let's take some metrics. All times are fair game, though more recent times count for more because places do change, and that should be acknowledged.

Let's check domestically.

Human Freedom Index (https://worldpopulationreview.com/country-rankings/freest-countries). United States scores 8.73 out of 10, ranked 15th out of 165 (higher is better). Russia scores 6.23, ranked 126th. China scores 5.57, ranked 150th.

Press freedom, using Reporters Without Borders 202 ranking (https://rsf.org/en/index). Russia is 155 out of 180. China is 175 out of 180. The United States is 42.

Global Peace Index (https://worldpopulationreview.com/country-rankings/most-violent-countries). United States is 2.34 (lower is better). China is 2.11 (better!) but Russia is 2.99 (worse).

So, your claim is patently false. These are widely-reported metrics where the U.S. is domestically far less oppressive, and less violent (marginally) than Russia.

It's harder to come up with good international metrics. Why don't you propose one and we'll check?

Note that metrics like "foreign wars started" alone isn't adequate, because this doesn't distinguish the hypothetical cases where a foreign war is conducted solely to rescue the people of a country from brutal and barbaric leaders, and where it is conducted brutally and barbarically for self-interested reasons. In cases where it's a war by proxy, the degree of proxying also needs to be assessed.

I don't think any foreign interventions meet either of those two extremes, but the U.S. invasion of Afghanistan is pretty far towards the first, while the U.S. support for Saudi Arabia despite its actions in Yemen are trending rather towards the second. Russia's invasion of Chechnya was--in implementation if not original conception--pretty far towards the second. The taking of Crimea is less clearly awful, but there wasn't an early-Taliban level of brutality to begin with, so the whole affair fails to meet the standard of the first extreme; at best it's middling. Given Russia's atrocious press and political freedom (see above), it's hard to find out how it's viewed in retrospect.
