“There's no magic to the phrase radical Islam. It's a political talking point. It's not a strategy. And the reason I am careful about how I describe this threat has nothing to do with political correctness and everything to do with actually defeating extremism. Groups like ISIL and al-Qaeda want to make this war a war between Islam and America or between Islam and the west. They want to claim that they are the true leaders of over a billion Muslims around the world who reject their crazy notions. They want us to validate them by implying that they speak for those billion plus people. That they speak for Islam. That's their propaganda. That's how they recruit. And if we fall into the trap of painting all Muslims with a broad brush and imply that we are at war with an entire religion, then we are doing the terrorist's work for them.”

“Maybe the critics are right. Maybe there's no escaping our great political divide, an endless clash of armies, and any attempts to alter the rules of engagement are futile. Or maybe the trivialization of politics has reached a point of no return, so that most people see it as just one more diversion, a sport, with politicians our paunch-bellied gladiators and those who bother to pay attention just fans on the sidelines: We paint our faces red or blue and cheer our side and boo their side, and if it takes a late hit or cheap shot to beat the other team, so be it, for winning is all that matters. But I don't think so. They are out there, I think to myself, those ordinary citizens who have grown up in the midst of all the political and cultural battles, but who have found a way-in their own lives, at least- to make peace with their neighbors, and themselves. ...I imagine they are waiting for a politics with the maturity to balance idealism and realism, to distinguish between what can and cannot be compromised, to admit the possibility that the other side might sometimes have a point. They don't always understand the arguments between right and left, conservative and liberal, but they recognize the difference between dogma and common sense, responsibility and irresponsibility, between those things that last and those that are fleeting. They are out there, waiting for Republicans and Democrats to catch up with them.”
