...And unpredictability can spread: one powerful outlier can pave the way for others, and as more states joint the outlier, the foundations of the rule of law begin to crumble.US counterterrorism practices--and the legal theories that under-pin them--are undermining the international rule of law in precisely this way...

It has often been our best instincts, not our worst, that have led us to do harm in the world

I don't believe that humans can be reduced to homo economicus, but as a group, government officials are remarkably sensitive to financial, political, and reputational costs. Thus, when new technologies appear to reduce the costs of using lethal force, their threshold for deciding to use lethal force correspondingly drops. If killing a suspected terrorist in Yemen or Somalia or Libya will endanger expensive manned aircraft, the lives of U.S. troops, and/or the lives of many innocent civilians, officials will reserve such killings for situations of extreme urgency and gravity (stopping another 9/11, getting Osama bin Laden). But if all that appears to be at risk is a an easily replaceable drone, officials will be tempted to use lethal force more and more casually.

We prefer to imagine brutal wars and atrocities as events that just happen every now and then, much like tornadoes or lightning strikes; this metaphor suggests that we can't generalize from them, since they are radically discontinuous with ordinary life. But wars and atrocities do not just happen: societies and individuals slide into them, little by little, one tiny decision or omission at a time. (p214)
