The United Nations Security Council is one of the primary organs of the United Nations, which
is primarily responsible for the maintenance of international peace. It is also a significant battleground
for great-power politics where the permanent members of the Council (the United States, Britain, France,
Russia, and China) constantly engage in mutual confrontation and cooperation. This study analyzes the
official meeting records of the Council using large-scale text analysis methodologies such as word embedding.
Focusing on one of the most consequential notions for the Council deliberations, ”threat to the peace,” the
study quantitatively represents the members’ conceptions concerning this notion, and rigorously measures
the discrepancies among these conceptions. The study thus clarifies how the polarization among the major
powers has unfolded over the past decades.
