When I asked the European ambassador to talk to me about America’s deepening partisan divide, I expected a polite brushoff at best. Foreign diplomats are usually loath to discuss domestic U.S. #politics.Instead, the ambassador unloaded for an hour, warning that America’s poisonous politics are hurting its security, its economy, its friends and its standing as a pillar of democracy and global stability.The U.S. is a “fat buffalo trying to take a nap” as hungry wolves approach, the envoy mused. “I can hear those Champagne bottle corks popping in Moscow — like it’s Christmas every fucking day.”
