I remember other bad times - the threat of nuclear armaggeddon in the '50s, the Viet Nam war, the confrontation with Russia over Cuba. But none of those felt like this.
Those were classic military confrontations with a foreign enemy, or bitter political disputes. This is a world-wide breakdown in civilized behavior, a challange to basic values. Sometimes good things happen when people have to rethink basic assumptions but it's pretty hard to see the bright side.
