What is happening at the southern border is a true and actual crisis. News accounts justly use words like chaos, collapse and breakdown. They feature images of children—toddlers, 4- and 5-year-olds—being shuffled to warehouse holding centers, sleeping crowded at night on what look like pallets, covered only in Mylar blankets. "I never thought we'd have refugee camps in America," said Texas Sen. John Cornyn, "but that's what it's appearing."

All this gives normal people a feeling of besiegement and foreboding. Is a nation without borders a nation? Washington's leaders seem to recognize what's happening as a political problem, not a real problem. That is, they betray no honest alarm. They just sort of stand in clusters and say things.

There seem only two groups that view the situation with appropriate alarm.

One is the children themselves, dragged through deserts to be deposited here. To them, everything is a swirl of lights, color and clamor, and shouting and clanking. A reporter touring a detainment center in Texas noted a blank, lost look among some of the younger children. Every mother knows what that suggests. Children who cry and wail anticipate comfort: That's why they're crying, to alert those who care for them that something is wrong. But little children who are blank, withdrawn, who don't show or at some point know what they're feeling—those children are in trouble.

The other group feeling a proper alarm is normal Americans, who are seeing all this on TV and who judge they are witnessing a level of lawlessness that has terrible implications for the country.
