When so many lives are at risk, when so much killing is going on, when there's so much chaos and suffering, isn't the risk warranted? ... And if we don't take the risk of coming to the conference, what do we do? We let it continue?
In fact UN is more of a galaxy of organisations and agencies than one machine.
I don't see a situation where one side will win militarily, take over Syria, and there will be peace and quiet, a clean victory.
I urge the Iraqi leadership for sake of its own people... to seize this opportunity and thereby begin to end the isolation and suffering of the Iraqi people.
UN peacekeeping operations are now increasingly complex and multi-dimensional, going beyond monitoring a ceasefire to actually bringing failed States back to life, often after decades of conflict. The blue helmets and their civilian colleagues work together to organize elections, enact police and judicial reform, promote and protect human rights, conduct mine-clearance, advance gender equality, achieve the voluntary disarmament of former combatants, and support the return of refugees and displaced people to their homes.
World Health Day is an opportunity to highlight the problem, but above all, to stimulate action. It is an occasion to call on all partners - governments, international donors, civil society, the private sector, the media, families and individuals alike - to develop sustainable activities for the survival, health and well-being of mothers and children. On this World Health Day, let us rededicate ourselves to that mission.
All our efforts to defeat poverty and pursue sustainable development will be in vain if environmental degradation and natural resource depletion continue unabated.
We must bring a message of solidarity, of mutual respect and, above all, of hope. Business cannot afford to be seen as the problem.
Let us remember the large numbers of citizens who, day in and day out, through acts of volunteerism large and small, bring hope to so many of the world's disadvantaged. Let us ensure that this wonderful resource, available in abundance to every nation, is recognized and supported as it works towards a more prosperous and peaceful world.
Fierce national competition over water resources has prompted fears that water issues contain the seeds of violent conflict.
You will recall that for months after 9/11, there was incredible support and sympathy for the US. I really hoped and wished they had played on that, and kept all these friends they had made, and found a way of dealing with the terrorists through co-operation of international intelligence services, police exchange of information.
Revolution by its nature can not be overly programmed or directed. There are so many forces at work that you don't know where and how it all ends.
By signing the Oslo accords in 1993 he took a giant step towards the realization of this vision. It is tragic that he did not live to see it fulfilled.
Remembering is a necessary rebuke to those who say the Holocaust never happened or has been exaggerated.
Sometimes when you take a tough action against one side in the conflict, they see you as part of the conflict and they attack you.
If we do not get a universal acceptance of the constitution the likelihood of the violence continuing is there. If it had been an inclusive exercise -- as when everybody had embraced the constitution and everyone saw his interest protected by the constitution -- I think it would have been a rallying exercise. We are not there at this stage
When the US withdrew their troops from Somalia, I recall making a comment that [in] the way the peacekeepers had been withdrawn from Somalia, the impression had been given that the easiest way to unravel a peacekeeping operation is to kill a few soldiers.
I was devastated by the atrocious bombings that struck London today. These vicious acts have cut us all to the core, for they are an attack on humanity itself. [7th July 2005 - on London bombings
Sometimes in peacekeeping operations you show force in order not to use force - people realise that there's a pushback and there's a solid force there that's not going to be pushed around, that sometimes helps.
The young and dynamic and idealistic people in the square do not have the chance to organise themselves politically, to be able to follow through their dreams in six months time, to play an effective role in the future.
Many African leaders refuse to send their troops on peace keeping missions abroad because they probably need their armies to intimidate their own populations.
I believe that our world needs an instrument of global action as never before in history. I believe that the United Nations is the instrument for securing peace and for giving people everywhere, in poorer countries as in richer, a real stake in that peace by promoting development and encouraging cooperation. But the United Nations is only an instrument, an actor in need of props and cues from its directors, And so I will paraphrase Winston Churchill: Give us the tools-the trust, the authority and the means-and we will do the job.
Nelson Mandela stands as an inspiration to us all
It is tragic that so few young people in Western democracies vote. They have forgotten that their ancestors fought for the right to choose and change their leaders. They don't realise that their votes are more important than their tweets or Facebook posts.
The report produced by my commission, the Global Commission on Elections, Democracy and Security, in 2012 showed the corrosive impact of money in US politics, for example, which undermines the legitimacy of the democratic system in citizens' eyes. Such perceptions partly explain the rise of a phenomenon like the success of Donald Trump.
