About this interactive
Countries to the left with nuclear power but no weapons are listed in order of the total number of current operable civilian reactors connected to the grid to generate electricity.
In the centre and to the right, hover to see countries' nuclear status and the total military inventory of weapons that are considered operational (strategic and nonstrategic), reserve and stockpile.
In addition to the nine countries that have their own nuclear weapons, shaded American flags indicate the five countries hosting US nuclear warheads under NATO sharing agreements.
