Good thing it's not like the solution to then Growing Anti-Semitism in the USA,
as happened in 1933 Germans with Socialist Sympathies flooding into the USA legally and illegally,
to infiltrate,
Or the Foreign Born NKVD Russian Spy as Immigration & Naturalization USA Democrat Congressman
that questioned the Porous Borders that brought a European Problem into the USA
and made it an American Problem needing Solved within a decade.
Fascists Germans vs. Marxist-Leninist-Stalinist Commies at the doorstep then,
what sort now?
