If you are experiencing a lack of factual knowledge, then here is a refresher course for you:
U.S. Secretary of State James Baker’s famous “not one inch eastward” assurance about NATO expansion in his meeting with Soviet leader Mikhail Gorbachev on February 9, 1990, was part of a cascade of assurances about Soviet security given by Western leaders to Gorbachev and other Soviet officials throughout the process of German unification in 1990 and on into 1991, according to declassified U.S., Soviet, German, British and French documents posted today by the National Security Archive at George Washington University

Western leaders gave multiple assurances against NATO expansion to Gorbachev in 1990-1991 according to declassified American, Russian, British, Germans documents

Another hole in your factual knowledge is that Gorbachev had sought to reform the economy of the Soviet, ran into the ground by Bolshevik numbnuts. The sheer magnitude of cost to upkeep Warsaw Pact, the bloodletting of Oil sales (sold in USD) and the vast resources wasted in an arms race against the West.
This was the basis of the dissolution of the Soviet Union, and what Russia (a former member of the Soviet Regime) wanted, was security guarantees and to be partners with the West, since there was no communism to hinder friendship.
What the West actually did was LIE about not expanding NATO to the east and along with that, destroying an economically independent Yugoslavia.
As for Soviet glory, you seem to be living in some parallel dimension where delusions engulf you. Because in this world, the reality and facts clearly show that three times in history it has been the WEST who has attempted to invade Russia and kill its population. Be it the Teutonic Knights of the Holy (yeah right!) Roman Empire invading Russia in the 13th Century, or Napoleon's France invasion of Russia in the 19th Century, or Hitler's Nazi Germany invading Russia in the 20th Century.
Russia has very God given right to oppose and thwart any Western expansion of NATO, which happens to be .... as per its own charter declaration .... a defensive alliance. Now I do not whether the people in NATO are retarded or have just sought to decieve the world about what NATO is in reality. But a defensive alliance does not expand or be belligerent as NATO has shown in its track record, destroying countries with bombings and sponsoring terrorists in Libya, Syria, Afghanistan, Mali, Yemen, Somalia and Yugoslavia .... that too, I would like to add, without any authorization from the United Nations Security Council.
So kindly go get up to speed on the NATO charter, the lies told by Western warmongers, the facts recorded yet brushed under the carpet to hide the truth.
