The right wing parties act as if we could just return people to Syria, Afghanistan and whereever just as we wand, no questions asked. That you need to cooperate with these countries to return people there...
Which we can't really return since that would mean cooperation with the Taliban. And even if we could cooperate, the countries then don't want them back or will demand various favors or bribes in return so then you're basically funding some terrorist regime to return 3 illegal migrants.
