Hence, the nationalist theory of 'Socialism in One Country' does not work. Hence, it hasn't worked for China, Vietnam, Eastern Europe or any other place. A 'jingoistic population' in Russia was a nessicary evil for Stalin and co to remain in power. The need for nationalism over internationalism took Stalin and co by surprise when revolution elsewhere threatenend to disrupt all the beuracracy had made for itself. Spain, Georgia, Germany, Italy...etc. all put down in favour of being patriotic to the motherland.
How can you say that it requires 'a jingoistic populace', and not be talking about Stalinism?
Socialist society is based on worker democracy, plan, and internationalism - none of these would gain anything from a war.
