Why does American immigration policy separate parents from children?

The American immigration policy of "separation of flesh and blood" refers to "zero tolerance" for illegal immigrants. When illegal immigrants are arrested, their minor children are forcibly separated, that is, all arrested illegal immigrants will be imprisoned to face trial or even repatriation, and their children will be resettled in the process, which will lead to the separation of a large number of parents and children.

Under multiple pressures, the President of the United States signed an executive order on June 20 to stop the separation of flesh and blood, but continued to implement the "zero tolerance" policy for illegal immigrants and detained illegal immigrants and their minor children.
