TOUGH ENOUGH? Jonathan Gewirtz writes: “Tom Smith is cautiously optimistic about the possibility of Hillary Clinton as president. I am not so optimistic. . . . Leaders and voters in democratic countries are sometimes tempted to put unscrupulous people into positions of authority, under the belief that such people will not hesitate to do what has to be done in tough situations. But unscrupulous people, by definition, have their own agendas, and it is a delusion to believe that they will provide some kind of short cut around the hard work, hard choices and pain of winning a war.”
