Quivers in Ukraine. A passenger jet was shot down mysteriously. Today there are reports of two military jets downed.
These are reasons for worry, of course. We always have those, but these are not enough, I think, to fear that World War III will break out next Tuesday.
Vladimir Putin, and whoever succeeds him in his job, will presumably worry more about keeping Russia dominant in what used to be the Soviet Union than about scuffing with the United States. Barack Obama seems a moderate with no haste for a World War III. Let's hope his successor shares that view.
History courses emphasize wars; they're dramatic, but we have had times of peace and enjoyed them. Let's work to have more.
