The first is historical factors. At that time, these Warsaw Pact countries were unwilling to participate in the Warsaw Pact, and they were all forced by Russian tanks and bayonets.

Needless to say, East Germany was a garrison of Russian soldiers. Later, I went to West Germany, and naturally I didn't pee on Russian soldiers.

Poland, isn't russian cuisine enough for people? Not counting Russia at that time, it is said that the loving father and moustache joined hands to annex Poland and killed more than 20 thousand elites in Katyn and other places. Poles have never trusted Russians.

Not to mention Czechoslovakia and Hungary, just look at history.

Even in the Ku era, Romanian hair was close to each other.

There is only one Bulgarian left, and he has a little affection for the Russians.

If you think so, these countries have little affection for the Russian people, and there are still many conflicts in history. They finally got a chance to come out. Why do they want to form an alliance with the Russian people?

The second is objective economic considerations. The Russian people have no money, and the development of these countries needs money. Then we have to go to the European Union.

On the other hand, from the perspective of development, the trend of world economic integration is getting stronger and stronger. If you don't join, you will die sooner or later. Therefore, despite the pain, it is worthwhile to go to Europe as a big ship.

Russia actually has a limited military alliance with its brother Belarus.
