Frum is illiterate. This quote does not blame America for 9/11 but blames America for the disastrous wars that people like David Frum--W.

As I’ve explained here before, at this stage in my life, my main goal is to pass along the principles and templates I've learned with the hope that they can help others as much as they've helped me. One thing that has been incredibly valuable to me is learning that just because something hasn’t happened before in my lifetime doesn’t mean it won’t happen. So I needed to look not only at what the markets have been doing lately but to also study big events—like debt crises, internal political conflicts, and international wars—throughout history. For example, it was by studying the Great Depressi… wmi.edu.sg

Mathematician at UCLA, working mainly in harmonic analysis and partial differential equations. Writes What's new, a long-running blog on their research, open problems and expository notes.
It seems intuitive that a solved problem is unquestionably better than an unsolved problem: a magic button which, when pressed, turns the latter into the former at no cost would thus seem to be a "free lunch" that there would be no hesitation in pressing. But even such a benign-seeming operation as answering a question can have irreversible costs. One familiar example is that of spoilers to a movie one is looking forward to watching: knowing key plot points in advance may permanently decrease your ability to enjoy the movie for the first time. Similarly, leaking information about a competitio… Related

It is a quick read, an excellent book whose main virtue is not, in my opinion, direct analogy with the World War I, but a treatment of how in a multipolar world relatively small international events, misunderstandings, idiosyncratic fits of leaders, “hubris and fear” (as Westad often writes), resentment of the elite and of the public prodded by the media, can produce colossal miscalculations which then produce even more colossal wars and, in the era of the weapons of mass destruction, may end the civilization.

I think that sedentary armies, sedentary civilizations, they get stuck in ways, this is how we do it. And we're going to make it a little faster, we're going to make it a little bigger, a little stronger but this is how we think. Genghis Khan had no set way to think and, when he encountered the first walled cities around 1209 after founding his nation in 1206, he went out on these raids and I really think there were raids not wars at first.

A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
