But what really makes Trump’s America feel like a rogue state is the administration’s policy of taking children from migrants caught crossing the border unlawfully, even if the parents immediately present themselves to the authorities to make asylum claims. “This is as bad as I’ve ever seen in 25 years of doing this work,” Lee Gelernt, deputy director of the A.C.L.U.’s Immigrants’ Rights Project, told me. “The little kids are literally being terrorized.”

Family separations began last year — immigrant advocates aren’t sure exactly when — and have ramped up with the administration’s new “zero tolerance” policy of prosecuting everyone who crosses the border without authorization. Over two weeks in May, more than 650 children were snatched from their parents.

The human consequences have been horrific. Last week, The New York Times described a 5-year-old boy from Honduras who had been separated from his father and cried himself to sleep at night with a stick-figure drawing of his family under his pillow. The Washington Post reported that Marco Antonio Muñoz, a 39-year-old who is also from Honduras, killed himself in a padded cell after his 3-year-old was wrenched from his arms.

We will never know what torments besieged Muñoz when he took his own life. But Pramila Jayapal, a Democratic congresswoman from Washington State, recently met with migrant women being held in a federal prison, many of whom, she said, were forcibly separated from children as young as 1. Some had their kids physically torn from them. Others were told that they had to go have their photograph taken; when they returned, their children were gone.
