They

 

are flat out telling US 

what is going to happen if we intervene.

Chinese scientists war-game hypersonic strike on US carrier group in South China Sea

You are going to live to see 

Carrier groups

(emphasis on groups BTW)

go down in the Pacific.

(It's not a "fad" 

I assure you.)

"Military planners conclude the Gerald R. Ford and its fleet could be destroyed ‘with certainty’ 

in rare published report"

"The researchers said 24 hypersonic anti-ship missiles were used to sink the US Navy’s newest carrier and its group in 20 simulated battles"

It's considered 

"rare"

because they have done this in the past 

and just not published the results before now

The question you might wanna ask yourself then is:

"Why do so now?"

They are saying:

"Look

Here is what is going to happen 

if you interfere.

Just dont do it."
