Editorial
Bad for business and worse for security As of this writing, Russia’s invasion of Ukraine is just over three weeks old. Though Europe has seen its share of military conflicts, the current scale of the aggression directed against civilians in a sovereign European nation was virtually unimaginable only a few weeks ago. Given this timeframe, it is daunting to risk any perspective here when it could potentially appear reactive and...
