This is not only an attack on a respected leader, but democracy in Denmark as a whole. There is absolutely no space for these types of incidents in European society.
While this was an inexcusable assault, it appears that Frederiksen's staff have exaggerated this incident. The leader was not hit, but shoved, according to witnesses, and did not sustain any serious injuries.
There's a 50% chance that Denmark will rank at least 14th in GDP per capita (PPP) in 2030, according to the Metaculus prediction community.
