Even after reading your replies ... OK, I sort of see the point to the first cartoon after the explanations -- large sections of the (at least eastern and British) European public actually believe that to be the case -- even if I don't accept that this public would ever much be swayed by 'satire'.
The second is still a pure non-sequitur. Baffling, really.
I'd say it's taking the (moronic) idea that refugees come to Europe because they feel entitled to the West's level of material comfort by showing that the dead kid's goal was to get a McDonald's Happy Meal (instead of, you know, not dying from war/starvation).
