Former UN High Representative for Disarmament Affairs, Sergio Duarte, warns that the taboo against nuclear testing is at risk. That pressure to resume testing appears to be increasing, and the ongoing modernization of nuclear arsenals in several States could make their use justifiable and acceptable in a “limited” nuclear confrontation.
“Once the taboo against testing is broken, the whole normative structure painstakingly built by the international community to curb the spread of nuclear weapons and advance the goal of nuclear disarmament will risk unraveling. The entry into force of the CTBT is a vital element to prevent such a dangerous development
and will also help to prevent an acceleration of the nuclear arms race and an escalation of regional and bilateral tensions.”
