Horatioo, certain "government agencies" might try something like that, but I guarantee you, the US Military would not stand for it.
They are the single largest procurer of both firearms and ammo. To place them at the mercy of some other nation and what they thought of how our military is told to perform their job, by the same legislature that restricts their procurement methods... Strategically and tactically, it would be a non-starter.
Maybe, idk, I do know many politicians want to deny the pipeline for oil across the US. The only thing this accomplishes is to give China a more secure source for oil and the US a less secure source.
I don't think politicians are working for longterm benefit of citizens, but more for corporate interess and govt power.
Idk and you may be right.
