Russia does not rely on Ukraine to manufacture its rockets and the engines for Russia's ships. Ukraine stopped cooperation with Russia on space after 2014. Ukraine stopped manufacturing Zenit rockets in 2014. Russia has other rockets which are built in Russia

There is also Lev Pontryagin (1908-1988, born in Moscow). A Russian mathematician. Pontryagin's maximum principle is used for solution of topical problems of spacecraft motion control.

You are responding to Ukrainian propaganda. Don't take it seriously

This is the kind of propaganda that the Ukrainians have been fed since their independence in 1991. To summarize it: it says that everything good were made by Ukrainians in the USSR, and also trying to demean Russia. Some combination of delusion of grandeur combined with victim complex. And all that while Ukraine was doing worst among other former soviet states. They fucked up everything. They had aviation industry, space industry, shipbuilding industry -- they had inherited all that from the USSR. Nothing left. Everything decayed and disappeared even before the war.

Prime example of a Ukrainian nazi

There is a lot of phone scam that target the Russians. And often the scammers use calls via WhatsApp and Telegram.
As for "sabotage" - yes, your beloved Ukraine use scammers to involve the Russians in sabotage. First, they scam people out of all their savings then they say "we will return your money if you do this and that".
The phone scam that target the Russians has been going on for years and the scammers are mostly located in Ukraine. And it started years before the war.

They are not illegal. Your laws are not world's laws

Exactly. Nothing for Russia to gain from this. It's very likely Finland (on behalf of NATO) made that up to have an excuse to put more pressure on Russia

Your so called sanctions stop at the 12 nautical mile distance from your shores. Your government is not the world government and your laws are not the world laws.

Your calculations are just stupid. a) The ship can drag its anchor for several miles on. b) The cables are not evenly spread on the sea floor. They are laid between major cities

Comintern was dissolved in 1943. Even if the USSR helped the communsit party of Cuba that doesn't mean the regime was a puppet installed by the USSR. By the way Comintern was involved in founding of the Communist party of China too. Read about the history of CCP. But you said China chose it on their own

The USSR didn't install Castro and his regime in Cuba. Cuba is one of the countries that chose socialism on their own.

And? Did you read that? The inspectors didn't say anything about tires. (Ukrained lied about tires), And they heard explosions probably caused by drones.
UKraine bombed the towers using drones

There are no tires. (tires = Ukrainian lies). And IAE inspectors said "The IAEA team reported hearing an explosion today at the same time the ZNPP informed them that a drone had allegedly struck one of the plant's two cooling towers." https://www.iaea.org/newscente...
Ukranian drones droped the explosives

I said the IAEA monitors haven't reported any burning tires. How your "video evidence" contradicts what I said? Does it show IAEA monitors saying that there are burning tires there?

To blame that on the Russians of course. To pressure the west to give Ukraine more assistance.
