Deep down, do you harbor a horrible little suspicion  that accepting most migrants or refugees, (whatever you want to call citizens of other countries who want to live in America) is more moral than building a wall or stopping them at the border in any other way?  Deep down do  you suspect that it is more moral to help beggars in Bombay and derelicts in Djibouti than helping  your own sister?   Do any of the 535 legislators on Capitol Hill know of any moral framework defending national integrity?  Does any State Dept. bureaucrat know of any moral framework validating border control?  It sure doesn’t look like it, does it?  And if you don’t believe in the morality of it, how can you accomplish it?  No decent person can succeed at any enterprise that deep in his heart he considers morally reprehensible.  Deep down they and their European counterparts believe that any South American has the right to live in Texas or Arizona and they believe that any MENA (Middle East North Africa) resident has the right to reside in France, Italy, Germany or anywhere else in Europe. Yet, there is one moral response to uninvited immigrants; one blindingly clear and compelling approach to the problem that is entirely moral and which your rabbi imparts in this episode detailing what happened when they poured into his house.
