Sometimes an idea is so obviously good that one need only echo it, without any pretense of originality. Witness a proposal in the March 14 Wall Street Journal for a humanitarian airlift to save Ukrainian civilians.

Penned by Douglas Feith and John Hannah, both national security officials in the George W. Bush administration, the column made a distinction between a military no-fly zone and a purely peaceful air delivery of food, medicine, and other sustenance to innocents in areas bombarded by Russian artillery and effectively shut off from other outside aid. The Wall Street Journal editorial board endorsed the idea, too, and for good reason.
