The left is entering a new phase of ideological agitation — no longer trying to win the debate but stopping debate altogether, banishing from public discourse any and all opposition. The proper word for that attitude is totalitarian. It declares certain controversies over and visits serious consequences — from social ostracism to vocational defenestration — upon those who refuse to be silenced.

There is no comparing the brutality and cynicism of today’s pop culture with that of forty years ago: from High Noon to Robocop is a long descent.

We no longer have to search for a name for the post-Cold War era. It will henceforth be known as the age of terrorism. Organized terror has shown what it can do; execute the single greatest massacre in American history, shut down the greatest power on the globe and send its leaders into underground shelters. All this, without even resorting to chemical, biological or nuclear weapons of mass destruction. This is a formidable enemy. To dismiss it as a bunch of cowards perpetrating senseless acts of violence is complacent nonsense. People willing to kill thousands of innocents while they kill themselves are not cowards. They are deadly, vicious warriors and need to be treated as such. Nor are their acts of violence senseless. They have a very specific aim: to avenge alleged historical wrongs and to bring the great American satan to its knees.

Israel is different. In Israel the great temptation of modernity — assimilation — simply does not exist. Israel is the very embodiment of Jewish continuity. It is the only nation on earth that inhabits the same land, bears the same name, speaks the same language, and worships the same God that it did 3,000 years ago. You dig the soil and you find pottery from Davidic times, coins from Bar Kokhba, and 2,000-year-old scrolls written in a script remarkably like the one that today advertises ice cream at the corner candy store.

Highfalutin moral principles are impossible guides to foreign policy. At worst, they reflect hypocrisy; at best, extreme naivete.

I never had a Marxist phase. If I did it lasted a weekend, and it must have been a hell of a weekend because I don’t remember it...

To his credit, Obama didn't just come to Washington to be someone. Like Reagan, he came to Washington to do something -- to introduce a powerful social democratic stream into America's deeply and historically individualist polity.

I was a Great Society liberal on domestic issues. People ask me, 'How do you go from Walter Mondale to Fox News?' The answer is, 'I was young once.' End of answer.

The greatest threat to a robust, autonomous civil society is the ever-growing Leviathan state and those like Obama who see it as the ultimate expression of the collective. Obama compounds the fallacy by declaring the state to be the font of entrepreneurial success. How so? It created the infrastructure — roads, bridges, schools, Internet — off which we all thrive. Absurd. We don't credit the Swiss postal service with the Special Theory of Relativity because it transmitted Einstein’s manuscript to the Annalen der Physik.

Courage is not a quality one normally associates with mathematicians. Yet it should apply to people who work in their attics in secret for seven years without cease on a problem that has eluded the greatest mathematical minds since first proposed in 1637.

I’m not against a global pact to reduce CO2. Indeed, I favor it. But in the absence of one — and there is no chance of getting one in the foreseeable future — there is no point in America committing economic suicide to no effect on climate change, the reversing of which, after all, is the alleged point of the exercise. For a president to propose this with such aggressive certainty is incomprehensible. It is the starkest of examples of belief that is impervious to evidence. And the word for that is faith, not science.

Obsession with self is the motif of our time.

Every two years the American politics industry fills the airwaves with the most virulent, scurrilous, wall-to-wall character assassination of nearly every political practitioner in the country — and then declares itself puzzled that America has lost trust in its politicians.

We grow justly weary of our politics. But we must remember this: Politics – in all its grubby, grasping, corrupt, contemptible manifestations – is sovereign in human affairs. Everything ultimately rests upon it. Fairly or not, politics is the driver of history.
