Все аналогичные действия СССР были ответными шагами.
Well, I'd say that the annexation of the Baltic Republics (paging Nulle!) was an аналогичный шаг, but certainly not an ответный one, as it had occurred several years prior to the division of post-war Germany -- and, arguably, gave the US rational cause to be suspicious of Soviet language about establishing a "neutral" Germany.
