Only one of the countries you listed is a socialist country that "tankies" defend.
I listed countries that the people who accuse of being "tankies" defend. So-called tankies do not defend any of the countries you listed barring China, although we have plenty of criticisms of China as well. The only defence of Russia that we put up is that the conflict that is currently ongoing was caused by nato, and that no amount of pouring weapons into the country will save any lives, on the contrary it will in fact kill many more people. This is spun into "you support russia" by many but is an unfair characterisations of what those on the left actually believe. Yes you can probably find Z people to refute this but they are a minority. Russia is a capitalist shithole and we want to change that in the longterm just as we want to change it in every capitalist country.
