The Dark Ages truly are still here

Operation Wetback?

Well see ya later, Melania

I checked and it seems the one during Great Depression where it was 60% American was a different operation. Operation Wetback was 1954 and it says “some US citizens were deported” but doesn’t give numbers or percentages. For the Great Depression one it says

According to historian Francisco Balderrama, the U.S. deported over 1 million Mexican nationals, 60 percent of whom were U.S. citizens of Mexican descent, during the 1930s.

The program became a contentious issue in Mexico–United States relations, even though it originated from a request by the Mexican government to stop the illegal entry of Mexican laborers into the United States.

Huh

it also happened a lot before operation wetback.
