The figure above disaggregates compliance for each of the Article 1 prohibitions. Most importantly, the nine nuclear-armed states are not in compliance with either the prohibitions on developing, producing, manufacturing, or acquiring nuclear weapons or other nuclear explosive devices, or the prohibitions on possessing or stockpiling them.
The prohibitions in Article 1(1)(e) on assisting, encouraging, or inducing prohibited acts, however, stand out as the ones that are contravened by the greatest number of states. The nuclear-armed states’ retention of nuclear weapons is abetted in many ways. We find that a total of 11 states (Belarus, Belgium, France, Germany, Italy, Kazakhstan, the Marshall Islands, Netherlands, Turkey, United Kingdom, and United States) assist acts that are prohibited by the TPNW. Thirty-four states (Albania, Armenia, Australia, Belarus, Belgium, Bulgaria, Canada, Croatia, Czechia, Denmark, Estonia, France, Germany, Greece, Hungary, Iceland, Italy, Japan, Latvia, Lithuania, Luxembourg, Montenegro, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, South Korea, Spain, Turkey, United Kingdom, and United States) currently encourage or induce such acts.
The specific prohibition on allowing the “hosting” (stationing, installation, or deployment) of nuclear weapons is contravened by five states (Belgium, Germany, Italy, Netherlands, Turkey).
