NATO is a relic of Cold War hostility that belongs in a war museum not in a modern forum for diplomacy.
It would hardly be surprising if the eight Russians NATO expelled were indeed gathering intelligence, but we cannot know for sure. The most likely scenario is that everyone at NATO, Russian or not, is working as some kind of intelligence operative for his respective country.
Russia is right to end the illusion of dialogue and partnership when the reality is the other party is cynically offering to shake hands while trying to piss down your leg.
Western governments in the NATO military alliance are developing tactics of “cognitive warfare,” using the supposed threats of China and Russia to justify waging a “battle for your brain” in the “human domain,” to “make everyone a weapon.”
