I send my best wishes to you all at the Global Zero Summit, and for all the work you are doing to make the world safer for our children and theirs. I believe that a world free of nuclear weapons is not only achievable, but one of the most important policy objectives of our times.

The road to get there will be long. There is much work to do. And no one country will walk the road alone. But together I am confident that we can tackle the risks from proliferation and ensure the security of nuclear materials, as well as address regional instability and the many political, technical and institutional challenges that need to be overcome. It will be difficult, but I am pledged to do what it takes to enable all countries to give up their nuclear weapons, verifiably and irreversibly.

The NPT Review Conference in May presents the world with a vital opportunity to refresh and reinvigorate the cornerstone of the non proliferation regime. We must seize it.

I wish you all a very successful meeting as you take forward this important work.
