I would respectfully disagree with you that the U.S. is a safe place for refugees. The matter of A-B-, which was a decision that really precluded protection in gender-based claims, has not been overturned. Its application has simply been limited at the credible fear stage. A number of measures that the Trump administration is taking now eviscerate the credible fear proceeding, such as having border patrol officers rather than trained asylum officers carry out credible fear determinations—which is something really unheard of—and also changing the standards and the training for those border patrol to make it much easer for them to deny.
The main precedent, which really has precluded claims of women and people fleeing gangs, remains in force. It has not been overturned by any court as it applies to merits proceedings.
