I read about this 15 years ago. People were quibbling about whether to destroy the last remaining two samples (located in Atlanta GA, and Moscow I believe). Then, after the fall of the Soviet Union, we found out that they had TONS of liquid smallpox virus loaded in warheads, ready for launch to the U.S. I think it's safe to assume there's lots of smallpox hidden away somewhere.
