What everyone appears to forget is that the Russians have a deep national fear of being encircled, attacked, and destroyed. That fear did NOT start in the 1950s, or the 1900s, or the 1850s, or the 1800s, or the 1750s, or the 1700s, or the 1600s, or even the 1500s.
The way that the US government dealt with the Russians' culturally instilled fear was (after 1946) to encircle them, threaten to attack them, and demonize them as a nation that had to be destroyed.
This, of course, calmed the Russians down totally and they naturally treated the US government as a benevolent entity - right?
BTW, if it is OK for the US to "unilaterally intervene, militarily occupy, and transform sovereign states into political and economic protectorates" in order to protect (what the US government defines as) US national interests and security then why is it NOT OK for Russia to "unilaterally intervene, militarily occupy, and transform sovereign states into political and economic protectorates" in order to protect (what the Russian government defines as) Russian national interests and security?
