Open Letter to Pope Leo on the morality of Nuclear Weapons

Source: You Decide

Your Holiness,

A happy and blessed Pentecost to you and to all the faithful.

I write as a fellow believer and as Director of You Decide, a small Community Interest Company working on the ethics of nuclear weapons through the Nuclear Morality Flowchart. Our conviction is simple: nuclear deterrence is not only a matter of national policy. It is a personal moral decision. At the heart of everything we do sits one question: You shall not kill. Ever?

Your recent words moved us deeply. You warned that artificial intelligence must be 'disarmed,' deliberately choosing a word capable of awakening consciences and directing humanity toward moral responsibility. You also drew attention again to nuclear disarmament and the Church's enduring service to peace and human dignity. We stand in that same service.

Nuclear weapons exist in the name of citizens. They are funded by taxes. The leaders who control them are elected or accepted by the people they govern. If a person accepts nuclear weapons for their defence, then morally they hold them in their own hands. Responsibility cannot rest only with governments or generals, but with each of us.

The question therefore becomes personal:

Do I accept this? Do I think it is right? And if I do not, what am I willing to do about it?

The Nuclear Morality Flowchart, created by Martin Birdseye, guides individuals through the moral complexities of nuclear deterrence. It does not dictate conclusions. It insists these questions demand genuine moral engagement from everyone. The flowchart belongs in schools, parliaments, communities of faith and of no faith, and in daily life.

The flowchart is available in English, Chinese, Dutch, German and Farsi. Farsi is the language of people living through conflict and uncertainty right now. That is not incidental. It is part of the moral purpose of the work itself.

Our journey began in London, among people willing to think honestly about these questions, and it now aims toward a wider effort to move humanity away from nuclear weapons.

We see common ground between our work and the moral witness of the Holy See. We both seek to restore personal conscience to questions too often surrendered to systems and state power. We welcome the opportunity for dialogue that Your Holiness or your collaborators might consider appropriate.

The gap between those who decide and those who bear the consequences will not close by itself. It closes when enough of us decide that it must.

I respectfully invite Your Holiness to explore the flowchart at: http://nuclearmorality.com/

May the fire of Pentecost renew in all of us the courage to choose life.

I am, Your Holiness, most respectfully yours in Christ,

Jude Madubuike
