eventually these military aged chinese and mexicans will fill the military and be used to turn on american citizens when the time is right.
Chinese and other Asians have had a very low enlistment rate, relative to the population. These just arent very martial cultures, relatively speaking. I doubt that hordes of Asians are going to start enlisting anytime soon
Hispanics have a reasonably high enlistment rate.
And need I mention the draining away of all our high tech weaponry in Ukraine?
