If we can come up with innovations and train young people to take on new jobs, and if we can switch to clean energy, I think we have the capacity to build this world not dependent on fossil-fuel. I think it will happen, and it won't destroy economy.

The other thing that really I regretted not being able to do was to push effectively for the reform of the Security Council. Because the world was changing, and is changing very fast, and I felt the UN was holding on to old arrangements. Most governments felt that it has such a narrow power base, based on the results of the second world war.

Intelligence can be used to manipulate.

There was a time, with the Berlin Wall down, that [it looked as if] the UN finally could do what it was set up to do, the rivalry between the two camps would dissipate, and we could all co-operate. And then, of course, Iraq came and blew it all apart. These upheavals will always take place in the world, and the design and construct of the UN ideally should be such that it can deal with these upheavals, and possibly influence them, and survive and thrive, but it doesn't work out that way, because as an organisation we are so dependent on the same member states.

There can be no doubt that these attacks are deliberate acts of terrorism, carefully planned and coordinated and as such I condemn them utterly. Terrorism must be fought resolutely wherever it appears.

The invasion and occupation of Iraq is illegal.

On this International Day of UN Peacekeepers, let us pay tribute to the men and women from countries across the world who serve selflessly, tirelessly and fearlessly in UN peacekeeping operations. Let us remember the heroes who have laid down their lives in lands far from their own in the service of peace. And let us reaffirm our commitment to building a world free from the scourge of war.
