On February 14, 2014, as the Second Conference on the Humanitarian Impact of Nuclear Weapons came to an end, conference Chair Juan Manuel Gomez Robledo—then deputy Minister of Foreign Affairs of Mexico—captured the sentiment in the room in the powerful last few words of his closing remarks: in global efforts toward the elimination of nuclear weapons, this conference marked a “point of no return.” His optimistic conclusion was met with a roar of applause.
Hosted by the Government of Mexico in the coastal state of Nayarit, this was the second of three conferences specifically focused on highlighting the catastrophic consequences of any nuclear weapons use—the first and third hosted, respectively, by the governments of Norway and Austria. A key recognition that emerged from this cycle was that a legal prohibition was necessary to remedy the anomaly under international law whereby every other category of weapons of mass destruction had been explicitly prohibited, except nuclear weapons, the most devastating of all.
As Mr. Gomez Robledo explained at the Nayarit conference, “we need to take into account that, in the past, weapons have been eliminated after they have been outlawed. We believe this is the path to achieve a world without nuclear weapons.” Against all odds, and despite the direct opposition of nuclear weapons states and their allies, that path was indeed followed. Nearly three and a half years after Nayarit, on July 7, 2017, the Treaty on the Prohibition of Nuclear Weapons was adopted by 122 nations at the United Nations in New York, with Latin American having influenced both process and outcome.
Not only had Mexico played a decisive role in laying the groundwork that led to the historic adoption of the TPNW, but every single state in Latin America participated in the negotiations and voted in favour of adopting the Treaty. Moreover, treaty negotiations were presided over by ambassador Elayne Whyte Gomez of Costa Rica, a country that continues to be among the TPNW’s strongest advocates.
More recently, on October 24, 2020, Honduras secured a place in nuclear disarmament history by becoming the 50th state party to ratify the TPNW. When it deposited its instrument of ratification at the United Nations, Honduras triggered the process that will lead to the Treaty’s entry into force, set to take effect 90 days later. On January 22, 2021, the TPNW will officially become part of international law, and it will bear an indelible Latin American mark.
