Above is a photo of Manhattan, New York City, in the year 1947, looking from Battery Park toward midtown. Here you see everything—the Staten Island Ferry Building at bottom, Wall Street to the right, the 59th Street Bridge crossing Welfare Island at upper right, and in the hazy distance, the Empire State Building—at that time arguably America’s most recognized symbol. In the aftermath of a war that had destroyed Europe’s and Japan’s industrial capacity, the U.S. was the unquestioned power on the planet, with massive economic might, a military that had taken up permanent residence in dozens of countries, and a growing stock of nuclear weapons. Two years later the Soviets would detonate their first nuclear bomb, shaking the American edifice to its core. Meanwhile, all around the world, the seeds of change were taking root. Below is a look at the world as it was in 1947.

These two shots show two wider angles of the Ivy Mike nuclear test detonated 31 October, 1952 (1 November in some time zones) at Eniwetok Atoll in the South Pacific. We’re reposting this test not because we’re running out of nuclear images (that’s not even remotely possible), but because it’s the only test we can find that occurred on the scariest day of the year, Halloween. But if it doesn’t frighten you, consider this—an independent, non-partisan report released today reveals that the U.S., Russia, France, Israel, China, Pakistan, India and North Korea are all expanding their nuclear arsenals.
