Vladimir Putin is an evil man, and he is intent on evil deeds, which include the destruction of the liberal world order that the United States has led and that has brought more stability, prosperity and freedom to humankind than has ever existed in history. He is exploiting the openness of our society and the increasingly acrimonious political divisions consuming us. He wants to widen those divides and paralyze us from responding to his aggression. He meddled in one election, and he will do it again because it worked and because he has not been made to stop. Putin’s goal isn’t to defeat a candidate or a party. He means to defeat the West.
