Josh Hammer, author of “Israel and Civilization,” explains why the United States’ billions of dollars in annual aid to Israel undermines both countries. “I think both countries would stand to benefit from phasing this out. I’m not saying that you cut off the spigot overnight. I’m not saying, frankly, that you do it in the middle of a very hot war. But over the mid to long term, it is very shrewd policy to face this down,” he says.
