Pragmatism will be required on both sides to overcome the deadlock between Cuba and the United States. It may be that any détente will have to begin modestly. The Obama administration may first try talking with Cuba about "neighborhood" issues like immigration, drug trafficking, and the environment. "This would be a good place to start. There's no political minefield to hold us or them back," reasons Philip Peters, a Cuba watcher at the Lexington Institute. That may not be the full breakthrough many have hoped for. But with half a century of mutual distrust and inertia to overcome, it may be the best that can be done.
