To be honest, it IS terrorism, by the very first definition.
First terrorists (named so) was revolutionaries (not bolsheviks, but other parties) in Russian Empire, who go to Government official's office and shot them in the face with Nagant revolver.
Look up Vera Zasulich, Dmitry Karakozov, Narodnaya Volya (organization), etc.
It is TRUE terrorism, not bombing Christmas parade or marathon.
