Mr. president, excellencies, my friends, we meet at a time when the obstacles confronting human progress are multiplying, obstacles to peace, obstacles to food and clean water, obstacles to finance, medicine and education, obstacles to movement and opportunity. Obstacles to technology, to the knowledge and infrastructure needed to use it, and increasingly, obstacles between nations, between communities, and between people who no longer agree on the same facts or trust the same institutions. War continues to destroy lives and communities. Even though the international community possesses more tools than ever, ever before to prevent conflict and to facilitate dialogue. The climate crisis is accelerating. Even though the science is clear enough for us to act, and many of the solutions are already known. And despite unprecedented global wealth, millions remain without reliable access to food, water, health or shelter. These challenges, my friends, are creating the crises of which we constantly speak, and at the same time, new challenges are emerging. Artificial intelligence is opening extraordinary possibilities in health, education, science, and productivity while also creating new risk of exclusion, exploitation, surveillance and the distortion of truth. And yet, the cooperation needed to confront these challenges is under strain. It is why I believe the theme this year is so apt. Restoring trust. Managing transformation. A united nation that delivers for all. The theme reminds us that we have institutions created to preserve peace, to advance development, and yes, to protect human dignity. The institutions are these very United Nations. We have shared principles grounded in sovereign equality, and in the recognition that our responsibilities extend beyond borders. The reality is that we understand that there is, regrettably enough, for us to be able to invest in prevention rather than waiting to finance reconstruction. We understand enough about the climate crisis to reduce the emissions that are warming our planet, and take the necessary steps for our populations to adapt. We equally now understand enough about the rapid development of AI to know that as we welcome its promise, we must anchor its development in a universal, humanizing framework that does not imperil our existence as human beings. The failure, my friends, to address these challenges, therefore, is not one simply of knowledge or capacity. It is a repeated failure to convert what we know into what we do. To turn principle into practice and global capacity into solidarity So beneath our many crises lies yet another one. And yes, it is a crisis of responsibility. Mr. president, that responsibility begins here in these halls.
