Guess Who Has the Most Nuclear Warheads? Russia.

The number of nuclear weapons in the world plunged from roughly 70,300 in 1986 to an estimated 14,900. That’s good news.

The bad news is that the nuclear weapons now are more devastating then they have ever been, and Russia now has more nuclear warheads than any country on earth, according to the Bulletin of the Atomic Scientists and the World Nuclear Forces overview in the SIPRI Yearbook.
