BTW, How did USSR won cold war?
Well until WW2 there was always a debate about whether decentralisation and competition (epitomised by the capitalist system), and the flexibility it offers, is a better or worse way of organising things than centralisation and planning (epitomised by the USSR's command economy).
The years since WW2, have provided an unequivocal answer: decentralisation leads to disorganisation and chaos, and competition results in wasteful use of resources, duplication of effort, and failed businesses. Centralised and planned systems always work better, and decentralised systems can not hope to compete.
This applies to economies (look how the USSR out grew and over took the Western capitalist bloc).
This applies to militaries (look how much stronger the USSR was, especially once it had integrated the new communist countries into a single combined communist state) than the multinational NATO alliance.
And this even applies to technology - Comnet (based around a single massive central mainframe built under Moscow, and remote terminals under central control) was always vastly more powerful and capable than the little known US "internet" which was based on idea of networking many more-or-less equal computers at multiple locations.
