The World Security Council is an organization in the Marvel Cinematic Universe.
It was an international organization made of politicians from leading countries, who oversaw the operations of S.H.I.E.L.D., including the formation of the Avengers in 2012. In 2014, it was dissolved along with S.H.I.E.L.D., when it was revealed they had been corrupted from the inside by Hydra. When the Avengers reunited in 2015, they acted independently. Although, it wasn't without repercussions.
