Well Foxy, your history.com link doesn't explain what you think it explains. It most certainly doesn't say, as you seem to think it does, that Yalta 'contributed' to the Cold War. Indeed in this regards it says "The Yalta Conference had helped to end World War II. But it now began to shape the ensuing Cold War."

NB: it shaped the cold war - didn't contributed to the cold war. It wasn't 'responsible' for the cold war as you claimed. The cold war was going to happen, Yalta just decided where the borders between the combatants would be.

Here's another link that adds to the history:

There's plenty more on the web.

If you put in the question on the web:

How did the Yalta Conference lead to the Cold War?

The explanation given is the following:

"As the Soviet Union expanded borders further west and
more nations were integrated into Stalin's communist
government the Iron Curtain separated the East from the
West."

"In the end what came from Yalta sparked the military,
economic, scientific, political, and ideological start
of the Cold War."

Again Foxy, there's nothing you've linked which supports your original claim that what you mistakenly call concessions given at Yalta was 'responsible' for the cold war. You've found nothing to support that assertion and you won't because its not even close to true.

Even the claim that there were concessions completely misunderstands the situation on the ground at the time of Yalta. There were no concessions, just recognition of reality.

I get that you are now in that mode where you post increasingly irrelevant links to try to avoid admitting what is obvious. And I do you the courtesy of assuming that you have the intellect to understand that in your anxiety to blame the cold war on the west, you over-egged the pudding. So I'll vex you no longer on your error.

History may have lessons.
The history of Yalta surely does.

"Yalta didn't exacerbate the Cold War. Yalta simply meant more enslaved nations were in the Warsaw Pact during the Cold War than otherwise possible."

I am reeling from the stupidity of that statement.

The Cold War finished when when the wall came down in Germany and other 'satellite nations' ousted their communist parties from power, many with elections.

To say that more 'enslave nations' being enveloped within the USSR didn't 'exacerbate' the Cold War is just inane.
