Evil does exist in the world. A non-violent movement could not have halted Hitler's armies. Negotiations cannot convince al Qaeda's leaders to lay down their arms. To say that force may sometimes be necessary is not a call to cynicism - it is a recognition of history; the imperfections of man and the limits of reason.
Barack ObamaAmerica must always lead on the world stage. If we don't, no one else will. The military that you have joined is, and always will be, the backbone of that leadership. But U.S. military action cannot be the only - or even primary - component of our leadership in every instance. Just because we have the best hammer does not mean that every problem is a nail.
Barack ObamaI will never forget that the only reason I'm standing here today is because somebody, somewhere stood up for me when it was risky. Stood up when it was hard. Stood up when it wasn't popular. And because that somebody stood up, a few more stood up. And then a few thousand stood up. And then a few million stood up. And standing up, with courage and clear purpose, they somehow managed to change the world.
