Please stop with this obsession with sources, unless you have sources to the contrary.

I never claimed that the USSR was a war machine. I was simply explaining why the complex had to pretend that it 'wasn't only that', as requested by abcd_f. If you accept that there was a cultural battle going on, this explanation requires no further sourcing. If you do not accept there was a cultural battle, I suggest a little Googling because this is not an extraordinary claim.
