Well, of course they don't admit there are any captive nations. They have their own propaganda. They present a picture to their own peoples, including the world, so far as they can, that we know is distorted and is untrue.
"Captive Nations" is a term sometimes used in the United States to describe nations under undemocratic regimes. During the Cold War, when the phraseology appeared and was more frequently used, it referred to nations under Communist domination, primarily Soviet rule.
As a part of the United States’ Cold War strategy, an anti-Communism advocacy group, the National Captive Nations Committee, was established in 1959 according to Pub.L. 86–90 by President Dwight D. Eisenhower. The American economist and diplomat of Ukrainian heritage Lev Dobriansky played a key role in it.
The law also established Captive Nations Week, traditionally proclaimed for the third week in July since then. The move aimed at raising public awareness of the problems of nations under the control of Communist and other non-democratic governments.
The original Public Law 86-90 specifically referred to the following Captive Nations:
Russian emigres living in US, criticized P.L. 86-90, because speaking of "Russian communism" and "imperialistic policies of Communist Russia" this law by implication equated the terms "Russian", "Communist" and "Imperialist".
Group of prominent American historians issued a statement claiming that PL 86-90 was largely based on misinformation and committed the United States to aiding ephemeral "nations" such as Cossackia and Idel-Ural.
Gregory P. Tschebotarioff, Stephen Timoshenko, Nicholas V. Riasanovsky, Gleb Struve, Nicholas Timasheff were among opponents of the PL 86-90.
