But protecting our way of life requires more than our military. Democracy can buckle when we give in to fear. So just as we, as citizens, must remain vigilant against external aggression, we must guard against a weakening of the values that make us who we are. That’s why, for the past eight years, I’ve worked to put the fight against terrorism on a firm legal footing. That’s why we’ve ended torture, worked to close Gitmo, and reform our laws governing surveillance to protect privacy and civil liberties. That’s why I reject discrimination against Muslim Americans. That’s why we cannot withdraw from global fights – to expand democracy, and human rights, women’s rights, and LGBT rights – no matter how imperfect our efforts, no matter how expedient ignoring such values may seem. For the fight against extremism and intolerance and sectarianism are of a piece with the fight against authoritarianism and nationalist aggression. If the scope of freedom and respect for the rule of law shrinks around the world, the likelihood of war within and between nations increases, and our own freedoms will eventually be threatened.

­　　So let’s be vigilant, but not afraid. ISIL will try to kill innocent people. But they cannot defeat America unless we betray our Constitution and our principles in the fight. Rivals like Russia or China cannot match our influence around the world – unless we give up what we stand for, and turn ourselves into just another big country that bullies smaller neighbors. 【此处小编感受到了深深的恶意并表示一万个不赞同！】

­　　Which brings me to my final point – our democracy is threatened whenever we take it for granted. All of us, regardless of party, should throw ourselves into the task of rebuilding our democratic institutions. When voting rates are some of the lowest among advanced democracies, we should make it easier, not harder, to vote. When trust in our institutions is low, we should reduce the corrosive influence of money in our politics, and insist on the principles of transparency and ethics in public service. When Congress is dysfunctional, we should draw our districts to encourage politicians to cater to common sense and not rigid extremes.

­　　And all of this depends on our participation; on each of us accepting the responsibility of citizenship, regardless of which way the pendulum of power swings.

­　　Our Constitution is a remarkable, beautiful gift. But it’s really just a piece of parchment. It has no power on its own. We, the people, give it power – with our participation, and the choices we make. Whether or not we stand up for our freedoms. Whether or not we respect and enforce the rule of law. America is no fragile thing. But the gains of our long journey to freedom are not assured.
