Now there has been a steady decline in the number of nuclear warheads over the past five years, but data suggests world powers are determined to hang on to sizable stockpiles for the foreseeable future.
This according to an annual report released Monday by the Stockholm International Peace Research Institute.
As of early 2014, nine countries still had a total of 16,300 warheads, down by around 5.6 percent from the previous year but the pace of reduction has slowed compared to a decade ago.
The report shows the U.S. and Russia possess about 93 percent of the world's nuclear weapons.
It identifies seven others as nuclear states namely, Britain, France, China, Pakistan, India, Israel and North Korea.
Pyongyang, according to the report, has six to eight nuclear warheads in its arsenal.
