Mr. Boris Johnson
Prime Minister
United Kingdom
In its integrated review of the national defense and foreign policy for the next 10 years
published on March 16, the U.K. government announced that it would increase the cap of its
nuclear warheads from the current 180 to 260.
With the entry into force of the Treaty on the Prohibition of Nuclear Weapons (TPNW) on
January 22, to develop, test, produce, possess, use or threaten to use nuclear weapons have all
become illegal. The recent decision of your government runs counter to this global trend. On
behalf of the only A-bombed nation, we strongly protest against, and urge you to retract the
decision.
The 10th NPT Review Conference will be convened on August 2. What is required to do in
the current world is to cooperate in tackling such imminent problems facing the humanity as
COVID-19, climate change, wealth gap and poverty, human rights suppression and gender-
related issues. To that end, the implementation of the previously agreed commitments is called
for, including “to accomplish the total elimination of their nuclear arsenals” (2000) and “to
achieve the peace and security of a world without nuclear weapons” (2010). The five nuclear
weapon states, including the U.K., should be held most accountable for their implementation.
According to an opinion poll in the U.K., almost 60% of the public supports the government
signing up to the TPNW. You must respond to the voice of the majority of your people in
good faith.
