I have been, and will remain, outspoken in my insistence that Israel has a right to live in peace and security.
In 2009, at the height of the global economic crisis, it was clear that we were seeing something new: the impacts of the crisis were flowing across borders at unprecedented velocity.
Some might complain that nuclear disarmament is little more than a dream. But that ignores the very tangible benefits disarmament would bring for all humankind. Its success would strengthen international peace and security. It would free up vast and much-needed resources for social and economic development. It would advance the rule of law.
Climate change, in some regions, has aggravated conflict over scarce land, and could well trigger large-scale migration in the decades ahead. And rising sea levels put at risk the very survival of all small island states. These and other implications for peace and security have implications for the United Nations itself.
The Czech Republic is a dynamic United Nations Member State, active on the Human Rights Council, contributing to the peaceful settlement of disputes, and helping other countries to achieve a democratic transition.
The burden for achieving disarmament cannot be borne by peace groups alone. Everybody, regardless of age, income, profession, gender or nationality, has a stake in this quest.
Chemical weapons simply have no place in the 21st century. Progress in this vital area will help generate momentum to meet our goal of eliminating all weapons of mass destruction.
My U.N. five-point plan focuses on preventing proliferation, strengthening the legal regime, and ensuring nuclear safety and security - an effort that was given good momentum by the Nuclear Security Summit held in Seoul earlier this year. The world is over-armed, and peace is underfunded.
Saving our planet, lifting people out of poverty, advancing economic growth... these are one and the same fight. We must connect the dots between climate change, water scarcity, energy shortages, global health, food security and women's empowerment. Solutions to one problem must be solutions for all.
When I was six, the Korean War broke out, and all the classrooms were destroyed by war. We studied under the trees or in whatever buildings were left.
Weapons of mass destruction violate more than individual lives - they cross international borders and jeopardize all people. They also drain resources that could be used instead for medicines, schools and other life-saving supplies. We must come together with even greater determination to prevent a WMD nightmare.
Sekarang, lebih dari sebelumnya, kita perlu menghubungkan titik-titik antara iklim, kemiskinan, energi, makanan, dan air. Masalah ini tidak dapat diatasi secara terpisah.
All women and girls have the fundamental right to live free of violence. This right is enshrined in international human rights and humanitarian law. And it lies at the heart of my UNiTE to End Violence against Women campaign.
To measure the success of our societies, we should examine how well those with different abilities, including persons with autism, are integrated as full and valued members.
One of the main lessons I have learned the last five years as Secretary-General is that the United Nations cannot function properly without the support of the business community and civil society. We need to have tripartite support - the governments, the business communities and the civil society.
