For generations, the United States of America has played a unique role as an anchor of global security and as an advocate for human freedom. Mindful … - Barack Obama

We, the people, still believe that our obligations as Americans are not just to ourselves, but to all posterity. We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations. Some may still deny the overwhelming judgment of science, but none can avoid the devastating impact of raging fires and crippling drought and more powerful storms. The path towards sustainable energy sources will be long and sometimes difficult. But America cannot resist this transition, we must lead it. We cannot cede to other nations the technology that will power new jobs and new industries, we must claim its promise. That’s how we will maintain our economic vitality and our national treasure -- our forests and waterways, our crop lands and snow-capped peaks. That is how we will preserve our planet, commanded to our care by God. That’s what will lend meaning to the creed our fathers once declared.

I believe a government that suppresses peaceful dissent is not showing strength; it is showing weakness and it is showing fear. History shows that regimes who fear their own people will eventually crumble, but strong institutions built on the consent of the governed endure long after any one individual is gone. That's why our strongest leaders -- from George Washington to Nelson Mandela -- have elevated the importance of building strong, democratic institutions over a thirst for perpetual power. Leaders who amend constitutions to stay in office only acknowledge that they failed to build a successful country for their people -- because none of us last forever. It tells us that power is something they cling to for its own sake, rather than for the betterment of those they purport to serve.
