I don't understand why you're concerned now. In 1950, America was fighting half a million Chinese troops who were supported by Russian pilots during the Korean War. Now shyt's about to get real?
OK
Of course shyt is gonna get real...
The usa wasn't fighting the Chinese directly back in the Korean war. But the usa also didn't want that smoke.
And the Soviets didn't want any of that smoke during the cold war. They backed down quite a bit..
But things of course change..
The Russians ain't the Soviets, and have been preparing since the mid 90s for this fight. So for them it hasn't be a question of if, but when for a generation.
and well China of course isn't the China of the 50s/60s. It's far stronger now and the usa well is past it's peak strength.
