What an absolute joke of a propaganda piece. China might qualify as a threat, but as has been amply shown recently Russia is a paper tiger. A tiny nation armed with hand me down retired military hardware has not only fought them to a standstill but actually pushed back into their own territory and this piece would have us believe they're some kind of military juggernaut poised to crush the US military.
This is also ignoring the strained ties between Russia and China lately and the close economic ties between the US and China. The US and China might not exactly be friendly with each other, but also can't really afford to be enemies. Russia on the other hand only exports oil, an increasingly devalued resource, and one that is readily available from multiple other countries.
