It's not really needed to be talked about- you could talk about it in reference to economic factors of the USSR
e.g. nomenklatura where the elite were living the "high life" so tp speak whilst there were deteriorating living standards. The cost of maintaining that could not carry on due to the significant arms race spending.
Also the abuse of human rights- USSR ignoring the agreement of Helsinki accords (1975), Charter 77 and dissidents speaking out agaisnt the corrupt leadership of EE countries.
"Empire by rape" ultimately the Soviet bloc was maintained by force- militarily imposed without the consent of people
evaluation of "Moral bankruptcy"lack of legitimacy in EE undermined Soviet communism and brought about it's collapse
population were disillusioned with hollow promises and harsh realities of life under Marxist- Leninism
It focuses on a structural factor as to why they were unable to sustain CW policies
Widens the debate beyond political leaders by focusing on LT factors
In short if it's possible you can mention it in passing- you will only really need to talk about key personalities, economic factors and EE and bring in moral bankruptcy as a means of supporting an argument.
Hope that helps
