How many Soviet republics were there?

Unlike some, I won't point fingers; I study history, I don't invent it.

I must have studied history poorly; all I do is make things up :( But does it turn out well?

But calling the system that existed in the USSR communism is the height of ignorance.

Alexey, please read the History textbook for grades 10-11 or buy a reference book and familiarize yourself with it. The height of ignorance is a joke. If you insist, I will quote three independent sources that use exactly that word. There were no communists or a Party in our country; there were Socialists? Don't make me laugh, dear Alexey. I can take a dictionary and then prove, point by point, that a phenomenon like communism did exist.

Do whatever you want in your Russia; I was only talking about the USSR and the danger of communism. At least your family is not subjected to repression, so it is easier for you to talk. Do you know Murphy's Law? No matter which line you are in, it will always seem to you that the second one is moving faster. As soon as you switch to the second one, the first one will start moving faster. Finally, your back-and-forth will start to annoy people in both lines. :) So, life always seems better where we don't live.

But the prosperity of the USA is built on the blood of the Indians.

A lie. Or ignorance. All the wealth flowed to Portugal and Spain, for your information. And the war with the Indians was different, when everything had already been plundered. Thousands of people from different countries flocked to America, where they built houses and raised livestock. No one justifies the colonists' policy of placing Indians in reservations, but prosperity was clearly not built on this. Territory, and only territory. The rest is culture and a nation formed by the colonists. The Indians didn't even want to be slaves.

Did you read that? Now, throw all those words out of your head. :) There's no need for us to argue about a past regime that almost no one remembers anymore.
