Imagine you broke down Belgium, etc the same way the US is broken down by state. You'd get even lower murder rates in many areas of Belgium, that would make the safest areas of the US look dangerous by comparison.
If you break down Belgium to parts that are similar in size to U.S. states, you end up with one Belgium.
(However, breaking up Belgium brings to mind some controversies: the motto of the country is "Einigkeit macht stark" or "Unity makes Strength"; after the 2010 election (June 13, 2010) it took 541 days of negotiations to come up with a functional government (sworn in on December 6, 2011).
Face it, the US done fucked up.
