How many people in the US have pictures of Jesus, of George Washington, of Lincoln, and of other people they like in their house? Il-sung and Jong-Il are their Washington and Lincoln. Only difference is they died more recently. People back in the 18th century couldn't plaster their houses on pictures of George and Abraham, but had they had the chance they definitely would have.
The small red ones? They're party pins, if I remember correctly. People in socialist countries are generally more politically active.
Most people only care about their own country.
