Eight countries. 2,055 nuclear tests. 71 years.

In the name of national security, eight countries have tested nuclear weapons all over the world since 1945, frequently near populated places. North Korea’s claim of hydrogen bomb test draws skepticism, condemnations.

The Washington Post has created a powerful online animation depicting nuclear weapons test blasts worldwide since 1945.

Of course, Hiroshima and Nagasaki were more than "tests" -- they were attacks on cities, killing hundreds of thousands, mostly civilians.

But, as Dr. Arjun Makhijani of IEER has documented, DOE listed even Hiroshima and Nagaski as "tests" decades after the attacks took place.
