On 23 January 2017, Ireland hosted an informal brainstorming meeting in Dublin for a small group of States that had been most supportive of the Humanitarian Initiative, including from the six core group States, to discuss expectations for the negotiations and ideas for the content of the new treaty. Among the negotiating States, the focus of attention shifted quickly onto the different expectations and what delegations wished to see in the future ban treaty. The Treaty on the Prohibition of Nuclear Weapons (TPNW) that emerged from the negotiations in June and July 2017 is the result of very fast-paced negotiations. The preamble of the TPNW contains 23 paragraphs and describes the motivation of the States negotiating the treaty and the rationale behind its adoption. The preamble refers to the longstanding goal of a world without nuclear weapons and the limited progress on the nuclear disarmament.
