So said President Donald Trump, on issuing his order halting the separation of children from parents caught breaking into the country. Trump's enemies are celebrating a victory. Yet the issue remains.

Under U.S. law, teenagers and tots cannot be detained for more than 20 days and must be held in the least-restrictive facilities. But if the children cannot be separated from the parents as they await trial, both will have to be released to keep families together.

We are back to "catch and release."

When that welcome news hits Central America, the migrant stream moving north will become a river that never ceases to flow.

The questions America and the West face might thus be framed:

Is there a liberal, progressive, Christian way to seal a 2,000-mile border, halt millions of migrants from crossing it illegally, and send intruders back whence they came? Or does the preservation of Western nations and peoples require measures from which liberal societies today reflexively recoil?
