It's ironic that Europe, which is much nearer to the USSR than the US, did not experience the same Red Scare as the US did with McCarthyism, and they continued to support nominally leftist/centrist/center-left parties in the years after. So the challenge is to have Europe experience the same anti-communist backlash (or even worse) as the US post-WWII.
Restrictions:
1. Yugoslavia is not invaded by the Soviets.
2. The Warsaw Pact does not lose members compared to OTL.
3. No WWIII.
4. South Korea is OTL.
5. Stalin still dies in 1953, and no hardliner (Molotov/Zhdanov) takeover.
6. No Morgenthau plan.
7. No Communist popularity upsurge in France and Italy post-WWII.
8. A socially conservative, economically progressive Europe by 2016
9. The EU is still formed.
P.S. It's strange how the 1956 Hungarian Revolution did not push Western Europe more towards the right. I mean Western Europe's much more liberal than the US (especially if you compare them with the Mountain West and the South).
