Answer:
"handing them a death sentence"
Step-by-step explanation:
The text shown in the question above reinforces the idea that the United States has not helped refugee children who are already very traumatized by the whole situation in which they are living. This is a very serious matter and it has to be dealt with at the level of severity that it imposes.
The author of the text admits that the United States has not only failed to help these children, but has put them in even more traumatic situations and then forced them to return to their country of origin, where they have fled war, hunger and misery. The text stresses that this is tantamount to giving these children a death sentence, as they are being criticized for helping and fleeing something very dangerous.
