Russia could have been part of the EU Not in the time frame you're implying. In 1991, the EU did not even exist in its current form (it was established in 1993). Eastwards expansion only started in 2004, when Poland and Czechia were among the first former iron-curtain countries to join. Putin became PM of Russia in 1999.
