Consider the United Nations

[Stinky The Clown]

In 1945, the UN Security Council had five permanent members. Two of the five are no longer so.

The five were the Republic of China [Taiwan], France, the Soviet Union, the United Kingdom, and the United States.

Taiwan still exists but somehow lost recognition as being China.

The Soviet Union simply no longer exists. Russia is not the Soviet Union. Russia is Russia.

Sure, treaties and accommodations and adjustments and other.

At the very least, it seems to me, veto power for China and Russia should be reexamined.

1. Too late. This should have been resolved years ago.

2. Taiwan is not considered a sovereign country by the UN.

Only 15 countries do but not the US or any European country. I don't think the Soviet Union was ever thought to be a country since Poland was part of the Soviet Union but was also a member of the UN.

3. Poland was not part of the Soviet Union.

Like other Eastern Bloc countries (East Germany, Czechoslovakia, Hungary, Romania, Bulgaria and Albania), Poland was regarded as a satellite state in the Soviet sphere of interest, but it was never a part of the Soviet Union.
