Now, from Jerusalem to New Mexico, walls were going up. So many lessons unlearned. The January assault on the Capitol could be merely a trough, a singular moment of shame to be discussed in wonder for years.

Only the backward look, the well-researched history could tell peaks and troughs from portals.
