The author argues that Russia, China, and other such states are socialist because they use central planning by their governments, have nationalized key industries, and allocated significant resources to acquire technological expertise. I would not identify them as socialist, but mixed economies. Also these countries have failed to take major steps to prevent the destabilization of the climate, but they are vigorously challenging a uni-polar world with the US/Anglo/Zionist Empire as the dominant power. Perhaps it can be argued that it was impossible to do both.
However, this may be an issue only of semantics. Otherwise his argument that these mixed ("socialist") economies perform much better than neoliberal economies, that is, the advanced capitalist economies that make up the Empire or that of former governments in eastern Europe that used central planning, sounds convincing. Regarding the latter, he writes:
In eastern Europe, capitalism, not socialism, brought about an economic collapse. As free market policies swept the region, the results were utterly catastrophic. Governments sold off state enterprises and let Wall Street and London set up shop. The result was mass unemployment; mass starvation accompanied a drastic rise in crimes such as the drug trade and human trafficking. However, amid the failure, the World Bank and the International Monetary Fund thundered that “free markets” and neoliberalism were the only way forward. Milton Friedman and Jeffrey Sachs became the respected voices, and their policies of deregulation and economic plunder expanded far beyond the former Eastern Bloc. In South and Central America, and in Africa, the promises of free market capitalism creating prosperity and abundance never materialized.His main thesis that the Empire fears the success of DPRK's economy is well argued.
