I recently argued that Sweden might return to their old neutrality politics because of their peaceful attitude. In Sweden the US is probably seen as a warring nation. However, here is an interesting statistic.
Sweden feature two important political assassinations. The prime minister Olof Palme in 1986 and the foreign minister Anna Lindh in 2003, both Social Democrats. There are 33 times more people in the US which would mean that we would assume that we would find about 67 political assassinations in the US, all things equal.
The assassinations of the Kennedy brothers and Martin Luther King and now Gabrielle Gifford, who is actually showing some vital signs, amount to only four. So, although crime rates are higher in the US, they don't seem to attack their politicians to the same degree.
