Ordering a million people in Gaza to evacuate when there’s no safe place to go, is not an effective warning. The roads are rubble, fuel is scarce and the main hospital is in the evacuation zone. This warning doesn't give license to harm the many civilians who can't or won't leave.

Whether it's Nagorno-Karabakh 3 weeks ago (!!!) or Gaza today, whether you call it ethnic cleansing or population transfer (both crimes, btw), respectable foreign policy elites quietly consider it a solution (unfortunate, but still) to the messy problem of the wrong populations in the wrong place.
