### Comment:
Thanks, you bring me back to my point of discussion : China has barely sold a portion of their holdings. If the trade wars continue further, China (+ other holders) will have no other option but to sell their US treasury holdings (dire need require dire actions). 
  
 What do you think will happen if China along with other countries get to a selling spree? 
  
 Also please consider this - fresh treasury sales did not go so well...

### REPLY:
A crash would happen and we'd all be in the stone age again. Which is why it's unlikely cause MAD. 
  
 Addendum to your OP: 
  
 12) a super duper advanced race of aliens appears over Washington DC, markets crash but luckily Will Smith and that guy from buckaroo banzai arrive and save the day.

### END.
