Thank you dear collegues.
The mathematical brilliance of this cartoon will not be noticed by readers who are not familiar with the topology of this type of puzzle. In the configuration shown, it would normally be physically impossible to "solve" the puzzle to place the refugees inside the ring of stars. There is, however, a "back door" solution: if one ALSO swaps two of the "blank" squares, then the rest of the ring CAN be solved so that the refugees are "inside".
