Why?
Well, as Pompeo stated, the Chinese have infiltrated the USA. They are inside our borders.
Luminaries on QV have pointed out that there are over 300,000 Chinese 'students' blanketing our nation's universities and research labs.
Add to these ranks the Antifa and BLM cadre, Iranian/Islamist martyrs-in-waiting, etc.
There are thus something more than 400,000+ potential irregular enemy combatants ready to roll in the USA right freaking now.
