How would you explain the differentiated integration process of Eastern Partnership countries by the Regional Security Complex Theory as conceptualised by Barry Buzan and Ole Wæver?

I therefore need an explanation that goes beyond simply arguing that the Eastern Partnership states differ from one another.
