The year 1955 or known as the cold war period, This period is known as the Cold War because there was no direct military engagement between the United States and the Soviet Union. However, this period was anything but “cold,” as multiple countries experienced internal violence as the U.S. and the Soviets supported competing factions fighting for power

And recently. USA have created NATO to fight the commiists and of course Soviet Union have created Warsaw pact to fight the capitalists as well

Soviet Union invited so many countries to join Warsaw pact and then he remembered that he's Geographically quite close to Yugoslavia, a communist country who has once said to him that "I'll be communist in my way" which both annoyed and concerned him because it could be a bad model to another communist countries but "it won't hurt to try and invite him right?" Soviet Union thought

And since they're Geographically close. Soviet Union HIMSELF come to Yugoslavia while Yugoslavia is teaching his kids how to exercise. Soviet Union waste no time as he quickly explained everything and his invitation to Warsaw pact with Yugoslavia and the answer Yugoslavia give him is "No"

Soviet Union: GASP IN COMMUNIST "W- WHAT DO YOU MEAN "NO"?! YOU DON'T WANT TO JOIN WARSAW PACT?!"
