For example, the US Navy has been made obsolete by Russia's hypersonic maneuvering Zircon missile.
For example, the speed and trajectory changes of the Russian Sarmat ICBM has nullified Washington's ABM system. One Sarmet is sufficient to take out Great Britain, or France, or Germany, or Texas. It only takes a dozen to wipe out the United States.
Why don't you know this?
For example, Washington's enormously expensive F-35 jet fighter is no match whatsoever for Russian fighters.
For example, US tanks are no match for Russian tanks.
For example, Russian troops are superior in their combat readiness and training and are highly motivated and not worn out by 16 years of pointless and frustrating wars over no one knows what.
