f you simply tally the number of warheads, the United States’ nuclear stockpile looks like a shadow of what it once was. The number of warheads held by the U.S. peaked in 1967 at over 31,000, but has been steadily declining, mainly through a series of treaties with nuclear rival Russia.
By February 2018, the deadline for the most recent treaty, the U.S. will have pared down its active strategic arsenal (warheads ready to launch) to 1,605, the lowest number since Dwight Eisenhower was president.
