'With no Ithaca awaiting' are humanizing mediums.
They tell you that people whose stories are mostly brought to you in generalizing numbers, are in fact individuals.
The news says that 100 people drowned, 72 people were rescued, 2200 people asked for asylum, 17300 people vanished at the Mexican border. But these pictures are not news facts: they show you persons, and sceneries. They show you that all people are different. When you look at the individuals in these pictures, you know what needs to be done, you know that spheres of kindness should be created where they can rest, be safe, have a good meal, play some stupid games, have a good conversation, sleep under clean sheets, take nice warm and soapy showers.
