OK, you know the Soviet Union MISSED the security council because it was BOYCOTTING the UN. Good.
Do you know WHY they were boycotting?
The Russian delegation to the Security Council did not attend the meeting because they were boycotting the United Nations for recognising Chiang Kai-shek’s government in Taiwan as the official government for China.
Taiwan wasn't expelled from the UN as the representative government of China until 1971; long after the Korean War had ended.
AS for Katyn, there's massive, indisputable evidence that Stalin ordered the execution of the Poles. Evidence that was available and proven long before the Soviet Union under Gorbachev formally admitted to the crime.
the Soviet Union under Gorbachev formally admitted to the crime.
You should feel special... you're probably one of the last folks on earth that know of Katyn that continue to deny that the Soviet Union was responsible for the mass murder of tens of thousands of Polish POW's. POW's captured, by the way, by a Soviet Union that violated the following agreements it had with Poland by attacking them in concert with the Nazis.
When the Soviet Union invaded Poland there were in effect the following treaties and agreements between the governments of Poland and the Soviet Union:
The Peace Treaty between Poland, Russia and the Ukraine signed in Riga, on March 18, 1921, by which the Eastern frontiers of Poland were defined.
The Protocol between Estonia, Latvia, Poland, Rumania and the USSR regarding renunciation of war as an instrument of national policy, signed in Moscow on February 9, 1929.
The Non-Aggression Pact between Poland and the USSR signed in Moscow on July 25, 1932.
The Protocol signed in Moscow on May 5, 1934 between Poland and the USSR, extending until December 31, 1945, the Non-Aggression Pact of July 25, 1932.
The Convention for the Definition of Aggression signed in London on July 3, 1933.
Why would they ignore these treaties? Because they had a new one with their new pals, of course.
On August 23, 1939 Hitler and Stalin signed a non-aggression pact, called the Molotov-Ribbentrop Treaty. Secret protocols of the treaty defined the territorial spheres of influence Germany and Russia would have after a successful invasion of Poland.
Oh... wait... that never happened right? No Molotov-Ribbentrop treaty?
Like I said... you could make millions on the comedy circuit.
You don't use "critical thinking" and you apparently NEVER "use a source from any side" except the Stalinist disinformation side.
