Less than 18 months later, the Kremlin released its updated military doctrine, which cemented “the intensification of the role of information warfare” in Russian foreign policy. One feature of modern military conflict, it said, is:
[T]he prior implementation of measures of information warfare in order to achieve political objectives without the utilization of military force and, subsequently, in the interest of shaping a favourable response from the world community to the utilization of military force.
A key task for modernizing the Russian military to be more effective in modern conflict, the doctrine concluded, is “to develop forces and resources for information warfare.”
This use of information warfare as a primary tool of warfare was put into play during the Euromaidan crisis in Ukraine, and later during the ongoing conflict in the Donbass region of Eastern Ukraine. Russia’s information operations about Ukraine have been so sophisticated and so extensive that it has become its own genre of research. (Source)
