Russia has been the subject of what Andrew Korybko calls “hybrid warfare” for decades. The only post World War 2 period when there was a lessening of the attacks was during the Yeltsin years in the 1990s. That period, when Russia’s economy was pillaged, was even more catastrophic for Russia than the sanctions and relentless negative propaganda that has ensued ever since.
The hybrid warfare, of which the sanctions are only a part, are a substitute for actual hot war which the neocon elements in successive American administrations have never taken off their agenda. That also is not a recent phenomenon.
