Why didn't Yeltsin, the leader of the former Soviet Union, open his door and embrace the United States? Instead of disintegration?

After the disintegration of the former Soviet Union, Russian President Yeltsin embraced the United States like other former Soviet Union countries and former Warsaw countries, hoping to ease the international situation and live in peace with other countries. In fact, the United States also gave Russia a big hug with open arms in the early days. At that time, Russia was totally committed to being a younger brother, and its military expenditure dropped again and again to a particularly low level, so that in the Chechen war, the Russian army suffered heavy losses and its attack was terrible, and even it was tied for a time. It is precisely because of the Chechen war that western countries have become hostile to Russia, and of course there are other reasons. The United States will not tolerate north-south division and launch a civil war, nor will Russia tolerate ethnic division and launch a Chechen war. Why not let me do it in Russia? First, I will listen to the boss. Second, it is also the premeditated hostility of the United States to Russia. Without Russia as its enemy, how could the United States unite a group of younger brothers? Must want a * * * with the enemy to create a * * * with interests. It is impossible for the United States to take this little brother with it from the bottom of its heart. Yeltsin was just fooled by the Americans. It was not until Putin's era that the true face of western countries was recognized, the boundaries were completely clarified, the country was strong, and the army embarked on the road of independent rise. It can be said that all kinds of setbacks in Crimea, Georgia, the Middle East and the West are caused by Russia, but in the final analysis, they are actually caused by Americans. Something happened in Georgia, and NATO ran faster than rabbits. It can be seen that Japan, South Korea, Vietnam, and various small countries in East Asia can easily become lackeys taken care of by the United States, while China and Americans can't really accept us today, nor can they tomorrow.
