National Review reports the arrest on espionage charges of three soldiers in the Pacific Northwest, charged with selling classified documents to China. All three have names strongly suggesting they are ethnic Asians, likely Chinese - Jian Zhao, Li Tian and Ruoyu Duan.
Do a Google search for "Chinese spy cases in the US" and you'll find most of the dozen or more so named perps appear to be ethnic Chinese. I don't think FDR had this much evidence when he interned the ethnic Japanese in western North America, with Canada's help.
It doesn't require much imagination to foresee the internment of ethnic Chinese then resident in the US in the event hostilities between the US and China break out. Who can forget Manzanar and the other 9 camps holding Japanese internees? If we win the war we can always apologize later; if we lose, we're screwed regardless.
If I were FBI director I'd be sure those conducting security background checks on Asian Americans in sensitive jobs were extra thorough. Occasional randomized rechecks might be justified.
As was the case in 1941, most of the target population is probably innocent, but sorting out collaborators in time of war ... isn't easy or quick.
The irony is that the CCP can bribe Asians living here using money we spent buying their heavily advertised Temu gimcracks. Hat tip to Lucianne.com for the link.
Afterthought: This is a problems nations with large immigrant populations share. One that low-immigration countries with homogeneous populations don't have.
Long-standing examples of the former are the US, Canada, and Australia. More recent examples include much of Europe with the exception of Hungary. China and Japan are examples of low immigration societies.
