I have been thinking about this but not in those terms...he really does not like Russia and thinks they are on a downward slope...same with China.  Sometimes I think he is playing to his audience...but he does cite facts at times -- particularly birth rates!!!
		
		
	 
I do think he’s directionally right on both Russia and China.  But I also think he’s a bit short on the timeframe to collapse.
Economies and populations that size can do a lot of stuff to stave off the collapse  and they will. But numbers is numbers, and they can only delay, not prevent it
Also, it’s highly likely that the true demographic situation for both is worse than stated.  Russia lies every time their lips move.  Plus they’ve lost a huge cohort of 18-34 year old men in the war that they can’t replace.   That’s a twofold problem because men in that group are typically prime age for both military service and making babies.
If they’re dead, maimed or have simply left the country, they aren’t available for either duty.
China’s published numbers are bad, and they’re lying through their teeth to make them look non-horrendous.
So Zeihan thinks the end for both is near.  I think it’s coming….but by hook and crook they’ll rock along for a while.  Then, when the collapse comes, it’ll be fast -- a lot like when the wall fell in 1989.  Lots of noise for a while, but nothing much happened until one day everything happened.  
Which probably means it’ll also be chaotic, violent, and it’ll be impossible to predict who will do what in the death throes.
A guy who’s shot multiple times might be  only a minute or two from bleeding out.  But if he’s hopped up on crystal meth or purple crunk or whatever, he can still do a lot of damage before he keels over.
