Dear @randahl, there are many other references that should be respected, although no NATO official statement. BTW, most Google findings in the NATO official site have been deleted lately.
Maybe you should take a look at a respectable book by Mary Elise Sarotte on the theme:

@randahl By the way, I suppose that neither the US National Security Archive nor Ms. Sarotte are Russian propagandists.
