I think that the US did have the right to prevent the spread of communism. Any nation that turned communist (except for Yugoslavia) turned out to be because the Soviets arranged it to threaten the US. For example; the Soviets used Cuba to place missiles in the Americas, and China used Vietnam to threaten NATO outposts in the South China Sea. Any nation that was communist was clearly aligned with the USSR, and determined to threaten the US.
They developed in the area known today as Israel and western mesopotamia, at first but then under the rule of emperor Constantine, many churches were build in rome.
