What was the purpose of nato and the warsaw pact?

The end of the story was gruesome–a spray of bullets and a splattering of blood on a wall in central Romania. On Christmas Day 1989, after a hastily arranged trial before a kangaroo court, the deposed Romanian dictator Nicolae Ceausescu and his wife, Elena, were executed by a firing squad. The assembled soldiers, eager to eliminate the despised dictator, were ordered not to aim higher than his chest. The faces of the condemned had to be recognizable after the fact. The country had to see that the communist era was over.

Hope it helps and have a really good day! :)
