Bret Stephens' masterclass in bad logic

Frightening images have emerged from Gaza in the week since a fragile ceasefire took hold between Israel and Hamas. In one widely circulated video, seven blindfolded men kneel in line with militants arrayed behind them. Gunshots ring out in unison, and the row of men collapse in a heap as dozens of spectators look on.

The gruesome scenes appear to be part of a Hamas effort to reestablish control over Gaza through a crackdown on gangs and criminal groups that it says have proliferated during the past two years of war and chaos. In the minds of Israel and its backers, the killings reveal Hamas’ true colors — and represent a preview of what the group may do if it’s allowed to maintain some degree of power.
