The rise of Cold War tensions didn't happen overnight. It happened during the daytime. (Actually, it happened little by little over years in a kind of slow creep.)

One of the first people to notice was British Prime Minister Winston Churchill. If there was one thing that guy hated it was slow creeps.

His "Iron Curtain" speech was a warning to the world that there was trouble brewing in Eastern Europe. His fancy-pants metaphor of a curtain made of iron descending right through the middle of Europe was eerily accurate—what does an iron curtain sound like? Yup: a wall. Winston Churchill basically predicted the Berlin Wall way back in 1946.

If history gave out I-told-you-so awards, he'd be first in line.
