Clearly, by 1949 a large proportion of the world had been divided along ideological lines – with one side aligned with the USA and the other with the Soviet Union. While these alliances were not specifically in conflict with one another, it was clear that a spat between any two members of opposing alliances could easily escalate into a much larger conflict.
