Luxembourg – 18th January 2026
AHA Luxembourg has joined a global civil society initiative to oppose a recent US Executive Order withdrawing the United States from key international organisations, conventions, and treaties. More than 60 organisations worldwide have joined the effort, forming a broad coalition representing hundreds of groups working on human rights, democracy, freedom of thought, equality, and humanitarian action.
The open letter, coordinated by Humanists International, warns that disengagement from multilateral institutions undermines the international human rights system and weakens global cooperation at a time of heightened geopolitical tension. Withdrawing from these mechanisms does not eliminate global challenges. Instead, it reduces opportunities for cooperation, accountability, and collective problem-solving, while creating a vacuum likely to be filled by authoritarian or malign actors.
Signatories also expressed serious concern about rhetoric targeting civil society and international NGOs, noting that such language endangers human rights defenders and erodes the global architecture designed to protect democratic values.
Commenting on the initiative, Gary McLelland, Chief Executive Officer of Humanists International, said:
“Humanists International’s engagement with multilateral institutions goes back to its founding in 1952. Coordinating this letter reflects that long-standing commitment and demonstrates that civil society is united in defending multilateralism, human rights, and international cooperation. Turning away from multilateral institutions makes the world less safe, less fair, and less accountable.”
Humanists International and the other signatories urge the US administration to reverse this decision and re-engage constructively with the international community, reaffirming its commitment to international law, cooperation, and shared global responsibility.
