Instead of the pendulum’s swinging back—a metaphor of inevitability that excuses people from taking a stand—the killing grew and grew, both in numbers and in cruelty.

How did educated, liberal society respond to such terrorism? What was the position of the Constitutional Democratic (Kadet) Party and its deputies in the Duma (the parliament set up in 1905)?

Kadets collected money for terrorists, turned their homes into safe houses, and called for total amnesty for arrested terrorists who pledged to continue the mayhem.

One sometimes hears that “the pendulum is bound to swing back.” But how does one know there is a pendulum at all, rather than—let us say—a snowball accelerating downhill?

Seriously.  Read it.  History doesn’t repeat, but it very often rhymes.
