I think they so it because there's really only 2 credible threats to the US and it's hegemony. China and Russia.
One of these threats is viewed as "exciting new markets" and is actively trying to buy or bribe it's way to the top. No points for guessing which one does this, but I'll give you a hint, the other one is Russia.
So since they are in bed with one foreign power that only leaves one credible threat to fearmonger about, because if you look too closely at the other you might actually see some stuff the powers that be don't want you to see.
