Terrorism is a significant threat to peace and security, prosperity and people.

Since [violence against women] is rooted in discrimination, impunity and complacency, we need to change attitudes and behavior - and we need to change laws and make sure they are enforced just like you are doing in Cuba.

Extreme weather events continue to grow more frequent and intense in rich and poor countries alike, not only devastating lives, but also infrastructure, institutions, and budgets - an unholy brew which can create dangerous security vacuums.

You are already leaders. Your ideas, your actions and your decisions make a difference. More than any other generation, you have a voice. Social networking is changing how we interact - and it can change our world. You are in touch with peers from around the world. You understand the power of instant communication. I appeal to you to use that power for the common good, the power of communication and the power of networking.

Climate change...is, simply, the greatest collective challenge we face as a human family.

I strongly reject threats by any member state to destroy another or outrageous attempts to deny historical facts such as the Holocaust.

Given the nature and magnitude of the challenge, national action alone is insufficient. No nation can address this challenge on its own. No region can insulate itself from these climate changes. That is why we need to confront climate change within a global framework, one that guarantees the highest level of international cooperation.
