Jefferson County’s connections to the big news stories of recent days— troops in Afghanistan, terrorism in Barcelona, racism in Charlottesville, confrontation with North Korea— are indistinct. But with North Korea warning Sunday of “the uncontrollable phase of a nuclear war,” confrontation is back. And so is belligerence. And so is the nuclear menace. Jefferson County isn’t likely in North Korea’s crosshairs. But if the confrontation turns uncontrollable, all of us could be the losers.
