“Certainly one of the chief guarantees of freedom under any government, no matter how popular and respected, is the right of citizens to keep and bear arms. This is not to say that firearms should not be very carefully used, and that definite safety rules of precaution should not be taught and enforced. But the right of citizens to bear arms is just one more guarantee against arbitrary government, one more safeguard against the tyranny which now appears remote in America, but which historically has proved to be always possible.”

Writing on the 15th anniversary of the Oklahoma City bombing

2010s
Context: p>Americans have more freedom and broader rights than citizens of almost any other nation in the world, including the capacity to criticize their government and their elected officials. But we do not have the right to resort to violence — or the threat of violence — when we don’t get our way. Our founders constructed a system of government so that reason could prevail over fear. Oklahoma City proved once again that without the law there is no freedom.Criticism is part of the lifeblood of democracy. No one is right all the time. But we should remember that there is a big difference between criticizing a policy or a politician and demonizing the government that guarantees our freedoms and the public servants who enforce our laws.</p

2009, Nobel Prize acceptance speech (December 2009)
Context: There has long been a tension between those who describe themselves as realists or idealists — a tension that suggests a stark choice between the narrow pursuit of interests or an endless campaign to impose our values around the world.
I reject these choices. I believe that peace is unstable where citizens are denied the right to speak freely or worship as they please; choose their own leaders or assemble without fear. Pent-up grievances fester, and the suppression of tribal and religious identity can lead to violence. We also know that the opposite is true. Only when Europe became free did it finally find peace. America has never fought a war against a democracy, and our closest friends are governments that protect the rights of their citizens. No matter how callously defined, neither America's interests — nor the world's — are served by the denial of human aspirations.
