“While we need to deprive the extremists of their safe spaces online, we must not forget about the safe spaces that continue to exist in the real world. Yes, that means taking military action to destroy Isis in Iraq and Syria. But it also means taking action here at home. While we have made significant progress in recent years, there is – to be frank – far too much tolerance of extremism in our country. So we need to become far more robust in identifying it and stamping it out across the public sector and across society. That will require some difficult, and often embarrassing, conversations. But the whole of our country needs to come together to take on this extremism, and we need to live our lives not in a series of separated, segregated communities, but as one truly United Kingdom.”

Twenty Year Vision for America (2004)
Context: We'll still need our armed forces and we'll take every necessary action to make America safe — but we'll gain that safety not by force of arms, but by who we are and what we represent. For we should be an America not puffed up by pride in our own power, but rather an America humbled by the recognition of our common humanity. We must make sure that globalization helps people around the world, raising living standards and improving the environment everywhere — rather than leading a race to the bottom.

The Irony of American History (1952)
Context: We take, and must continue to take, morally hazardous actions to preserve our civilization. We must exercise our power. But we ought neither to believe that a nation is capable of perfect disinterestedness in its exercise, nor become complacent about a particular degree of interest and passion which corrupt the justice by which the exercise of power is legitimatized.
